I wanna thank Jon and Judy and the rest of the team at TGA ...my wrx had a computer problem ..I had to have it towed to their shop and they worked some magic and drove the car home !!!....Jon worked with me on the tune and is very knowledgeable about the subarus!!!!...THANKS AGAIN GUYS YOU KEEP ROCKIN IT!!!!!

Their inspection is amazing. For $100, we got a thorough inspection on a vehicle wed just purchased.The service advisor talked us through all the issues with pictures to ensure we understand everything. She even helped us rank the items in order or importance!

The guys @ TGA have been an incredible team to work with. They remember your name and help you build exactly what youre looking for. John, their tuner, is on a completely different level and strives to make perfection happen every time. And the proof is in the dynotunes and after-tune checks ups. Do your CAR (not just subies) a favor and let these guys help you manifest your dreams.

From the front desk to the back dyno these guys and gal are professional and friendly and know their stuff. Theyve taken great care of me and my car. I would highly recommend them to anyone looking to tune their ride right.

Special thanks to Greg, Rory, and John for taking on this unique project of turbo charging my Corolla. It was definitely worth the long wait. Not only do these guys do amazing work, but they also care about the customer. They treat your car as if its their own and the proof is in their work. I recommend TGA Performance to everyone, whether you need a simple oil change to a very complex build like mine.

I only gave a 5 Stars because I had to, they didnt have 10 Stars to post! My husband needed to have his turbo replaced, engine, and God knows what else done. The list of repairs was huge. TGA was very helpful in explaining everything that was wrong and how they would be able to fix it. They did not pressure me into getting un-needed things. There was a few other things that needed to be done but they said I had plenty of time to get it done. They were very affordable. I was very happy that the only thing that I had to pay upfront was the parts. Since there was a lot of work that needed to be done, I was able to take time to pay off the rest. Alex made sure that he kept me up-to- date. Any time I had any questions, I knew I could call him at anytime and ask. When I got my husband car back, Alex made sure he explained everything to me that was done. I will be taking my vehicle in soon to get checked out and I dont have to worry about them saying that things are wrong that arent. They definitely have their customers as top priority! I would and will refer them to everyone that I know. They are the greatest!

I drove up from Pueblo to have some work done. Alex was very upfront about everything. My exhaust needed a little modification and the guys didnt cut corners. Everything came out awesome.. Great place!!!!

Customer service is above and beyond! TGA made me feel kind of like I was on Overhaul. Will be getting more work done by them in the future! I also definitely recommend TGA to anyone interested in getting a edge on the competition.

The bearing in my diff in my 370Z failed on my drive to ZCON in Colorado Springs. This happened on Monday of that week and I was able to find a replacement diff through Z1 motorsports on the Wednesday of that same week. The only problem now was finding a reputable shop to replace the old differential with the new one. All of the shops I called were booked out for the foreseeable future but when I called TGA, John spoke to his mechanics and they made a spot for me in their busy schedule. The Z1 diff assembly was shipped directly to their shop and it arrived Thursday morning and TGA installed it that same day. This made it possible for me to enjoy the events of Friday and Saturday at ZCON. Thanks to John and his team, my vacation and ZCON werent a complete let down. I also wanna thank John and his staff for helping me ship my old diff core back to Z1 so that I could get a refund, they show amazing professionalism and take care of their customers as needed. One thing I would advice TGA on is to make sure they tighten all the bolts on the exhaust when putting everything back together. My Y-pipe came loose from when it connects to the cats, which created an exhaust leak, since the exhaust has to come out to get to the differential, from what I believe.

They are booked out I came in today with a really simple issue and they told me what they thought it was super awesome they spent time talking to me when Im ready for my turbo motor definitely going with them

TGA did an awesome job on my fog lights and even got my oil changed. Alex was very helpful and friendly. I will definitely go back again

TGA has a great, honest and reputable team. From custom work, normal maintenance, to tuning- they can handle it all. Openly and honestly took responsibility for a small mistake made, as we all make mistakes, I know I have and they fixed the mix up with no issues or charge. Wouldn’t trust anyone else with the work I need done. They don’t settle for anything less than top notch and exceeded my expectations, especially for the tuning. Oh and the bearded guy at the front desk is cool too. Thank you TGA

Staff is very friendly and knowledgeable. Great place to get your car tuned. Will be returning

I do ALL my own car repair but when I rebuilt my WRX engine I needed a Cobb tuner and TGA Performance was absolutely great to work with. John B. the tuner, cares about you car like it is his. His communication via phone and email are great and he even sent me a limp map over email to get my car down to them for tuning. He spent a lot of time with me to explain the break in procedure and ensured I sent logs during the break in. He spent several hours on the final tune and it is great they post videos of the tune on their FB site.TGA service and support was great and I highly recommend them for any work for any make of car. My car is tuned now after engine break in and the car runs and drives like a new car.Seth

Excellent, local, veteran-owned shop specializing in Subarus, but great for any car or tuner. I was foolish and clipped curb and needed a new wheel. When I came in they were super helpful, no snide comments about the damage, and they really took the time to make sure we got the right part. They also got the wheel way faster than any other place in town said they could, and many shots wouldnt even order or, but wanted me to do it myself online. They got it mounted and aligned quickly and my WRX is back in business. Highly recommend this shop!

Subaru? This is your shop. The guys at TGA are veteran owned and Subaru experts. That being said, whatever your application is this shop can work on it. I come to this shop specifically because I know that I’ll have the peace of mind that my vehicle is going to be fixed correctly and to specifications.

Great shop and staff. Seem to know their stuff pretty good.

I recently had the great opportunity to have my 07 Subaru Impreza WRX STI, have a used car check, and a compression test. The customer service was tremendous! They went above and beyond explaining to me about my vehicle; they were patient and sincere with the questions I had. Worth the drive from Boulder to get serviced here! I highly recommend getting your car serviced by TGA Performance.

Had hopes up for this shop, all i wanted done was a full exhaust install and a tune, they told me they would have to have someone else tune it but that they could get it passed to them for me. They gave me an estimate weeks prior and a break down. And i agreed with it. Had an appointment set up. They called and said they would not be able to install my test pipe due to not having a tune and that it can effect my engine which was understandable. (I had paid the labor for the exhaust labor part of it and the tune obII reader piece which was $600 + tax. Before any of the work was done. So i assumed they would refund me most of the money considering they said they wont be able to tune it or install the test pipe. On the estimate it was supposed to be 375 total for just the exhaust portion of it but ONLY done the catback exhaust so i assumed i would only be part of that 375 not the full 375. Understood that it was a little more time due to the bolts being rusty and stripped but still charged me the full $600 because it required more time Completely ripped me off. And this is coming from someone who used to be a service writer for an autoshop. I also asked to check out one of my breaks due to grinding. and was told nothing about it. Id stay away from this shop and just go to a standard auto shop for something as easy as an axle back install. Or yet alone anything.

Shop diagnosed my engine with a rod knock initially and told me that my Subaru would last at most a year. After paying their invoice for a diagnostic I come to find the rod knock was not even a rod knock. Here I am over a year later with my vehicle running strong and out a few hundred for a misdiagnosis and having to pay for a retune :/. Tuning wise this shop is pretty good but mechanically I give a thumbs down.

TGA does not do their own alignments. I called them, asked if they did because I wanted a track oriented alignment, to which they stated yes, they do. I went to TGA because they are a performance shop with motorsport oriented ideals and experience. When picking up the vehicle, they showed me the alignment sheet, which was not within the spec that I had requested and told me they took it to Tire World to have it done. I took them outside to look at the car, and the aftermarket parts (coil overs and lower control arms) werent even used during the alignment. I was charged extra for a special / race alignment ($140) to have this done, only for them to shrug and tell me that I need to take it up with Tire World to get it fixed. Dealing with Tire World, they are unable to accomodate me because they do not have experience with these parts and are not comfortable making the alignment. I have a half dozen or more friends in the tracking/racing community that have similar alignments on near identical cars. TGA should not state they can do something they cannot. Im now out $140 for an unsatisfactory alignment and will have to pay again elsewhere to get this touched up.

Dont waste your money here.

John is the man when it comes to tuning! Alex is great and friendly and very knowledgeable on Subie parts!

Great service and they know Subarus!

Great place, friendly staff! Highly recommended.

They literally have a sign that says masks arent allowed in their store. Yikes.

Work performed was good quality however after spending close to $2,000 at the shop they threw away a valuable OEM part after swapping it out without any form of permission. Offered a very suspect explanation at best with no offer to compensate for the loss. Very disappointed in the integrity of the establishment after this experience.

These guys are awesome! If you have a modded Subaru and need something done this is where you need to be! They were super helpful and up front about the issue I took my car in for as well as helping make me aware of all the current issues with the car. There was no pressure to get everything fixed or anything for that matter! I am very satisfied with the repair they have already done and I can not wait to work with them for more improvements and maintenance in the future! Do yourself a favor and talk to these guys!

Nothing but the best service all the time. Had them work on 3 separate Jeeps, a CRV & an STi. Id go to them for anything.

Great individuals very Informed and take pride in their work

Amazing shop and great for anyone in the springs, I highly recommend them for the area being they are one of the far and few that are in the springs territory.

As a woman, going to an auto repair shop can be somewhat intimidating especially if you have no idea what you need. I was so blown away about how nice and helpful all of the guys were and how they took the time to present all my options and explain them to me in a way I could understand. I have a new-to-me 2006 Subaru Outback that had a lot of home garage work done to it by the previous owner and had been lowered in a way that made the ride incredibly bumpy and uncomfortable- the guys at TGA were able to fix my suspension and give me a smooth ride that didnt break the bank, and was much lower than I had been quoted somewhere else! Thanks, TGA. Youre my go-to for anything with my Subaru from now on.

Friendly and great service. Employees are very knowledgeable. They did my suspension and it came out perfect.

Love these guys and the owner is very considerate when it comes to budgets. I can see my 13 wrx having a great time representing this shop after its build is completed.

Best Subaru tuner in town and possibly Colorado. John is a FA20 wizard.

This place is great. Excellent customer service. Veteran owned and run. These guys can pretty much do anything for your subie. There new location is so much bigger then there old one. Its awesome!

Just got done getting an inspection done by them. Amazingly helpful as I transition from American muscle to Asian auto. No bs. They are really cool dudes who even helped me set up some stuff they didnt have too. 10/10 gonna have everything done through them.

Chad knows his stuff... get all your work done here.

After breaking my end links with a new lowered suspension on a Friday afternoon, Cisco and Dan were kind enough to take me in, and install and set up new end links and rear sway bar. The store was super clean, and those guys were incredibly friendly and helpful. The price was more than fair, especially considering that I was a last minute Friday night walk in. The work was excellent, and everything is aligned and set up great. And to top it all off, as I was leaving I had an issue with my battery and alternator, so they stayed even later to help me get the wiring sorted out. I can’t recommend the TGA shop and it’s staff strongly enough, excellent guys to work with and fantastic work! I live up in Denver, but would definitely consider driving back down to their shop for more work. 5+ stars!!

TGA is the only place I will ever reccomend work to be done for subarus. My wrx was severely abused by the first 2 owners, and TGA stopped at nothing to get it back to full health. John and his team stayed late multiple times with my car, and went through countless datalogs and map revisions until they were confident my subie was running like it should. Their incredibly knowledgeable and personable staff has earned a customer/supporter for life. Thanks guys!

Great service, knowledgeable people, and Decent prices.

Great shop, good group of guys. Knowledgeable and friendly, and willing to help you work within a budget.

These guys are life savers. I drove out here from Philly and as soon as I got to the Springs my car decided to overheat. AAA dropped me off at night and the owner came out. We talked and he was really understanding of my situation. He was a huge help beyond fixing my car and getting me back on the road. And he is incredibly knowledgeable. He doesnt fix more than what needs it. On top of that, his crew is really cool and friendly and gave me a ton of good info about the area and where to find some good hiking spots. Im almost glad my car broke down just so that I could meet those guys. So helpful and fair.

Really good people and they will work with you

These guys are the best! They always help. Impeccable customer. I trust them!

Great group of guys, everyone is super helpful and friendly they know their stuff for sure, will probably be the only shop I take my STI to.

My child sister could do a better job than TGA. Came here for an extremely basic 105k coolant system service on my 05 STi. I get my car back and it overheats immediately... Turns out, the hoses going to the coolant expansion tank had been switched. Ok. Not great, but human mistakes happen. Then, I start having coolant leaks. I take my car to Honest Accurate (couldnt recommend them more) and they said theyve never seen hoses and clamps in such terrible shape in their lives. Yeah. The clamps and hoses that JUST GOT REPLACED. The hoses were roughly cut to fit my car and the clamps were cheap and loose. THEN, the last thing that TGA touched failed. My water pump and timing belt. My water pump started leaking after only a few months and my timing belt got wet as a result. TGAs response was to bring it back to them to have them determine what the cause of the fail was and see what the cost would be to fix it. Would you bring your car back to a shop that butchered a simple service? Hopefully not. And I didnt either. They are the most pathetic excuse for a performance shop. I now tell everyone I know with a Subaru to go anywhere else.

After years of taking my Subaru to other shops around the springs, I have finally found the ONLY shop I will be going back to. These guys are true professionals through and through. And here is the kicker... I dont have a high performance Subaru. Nope. I have a regular old outback. And although these guys definitely also do killer work on the WRX and STIs, they treated my car like it was just as important. Very reasonable on price, and went above and beyond with the repairs that they did for me. Made a customer for life. And when I get my STI, this is the shop that Ill spend the money at to make it how I want. Thanks so much guys!

Awesome people and everyone is so helpful!

These guys are a local cos business. Very friendly and they do high quality work. Custom engine builds, turbos, fuel systems, whatever. Highly recommended.

Great shop! They kept me informed and went out of their way to save me money!

Top notch service from a great group of enthusiasts. The only place Ill go to have my Subaru serviced.

The crew were great. I don’t have a Subaru but they were able to get the parts I needed for my new vehicle ordered for me.

Started taking my car there when they were at the old shop, great crew, they did a used car check on my sti which id never seen before, fixed things they didnt have to and not even charged me, jake is a great guy and will definitely take the time to talk when he has it, dan at the front was always taking care of me, doing things for me most would never do, went to the new shop, was greeted by a new guy and was asking basic questions and he had no idea on most of the questions I was asking, I though it was odd when I first sat down at the front desk when he came out and immediately closed the garage door as if it was a top secret facility, all in all the mechanic crew is awesome and the shop is a great place.

I took my STI here because I was under the impression that this was a high quality shop. I had the absolute worst experience dealing with these people and after having the car for 5 weeks, they FAILED to fix the problem. On top of that, I contacted them and took the car back down to drive it with them and showcase the still existent problems. After pulling it into a bay for 20 minutes, they drove it back out and told me they had fixed it. They lied, AGAIN. After paying $3600 dollars to the shop for the labor and parts, I feel like my soul has been crushed. Ive never been more disappointed in any shops sense of integrity and honesty. And if anything, I hope this message reaches those of you who value your relationship to your car. Please do not trust these lazy amateurs.UPDATE: I took the sti to Heuberger Subaru and they replaced a wheel bearing. I specifically told your technition when we drove it that I thought it was the wheel bearing and he chuckled and waved it off. And please don’t try to pretend that you care to find a solution by trying to passively blame any further problems on the wreck when you had the car for FIVE WEEKS. Like I said before, LAZY AMATEURS.

Very friendly took my 07 sti in for a clutch replacement and were super fast turn around time. I would return my sti back to them anytime especially for any other maintenence on my sti.

Extremely unhappy. Would not recommend!

I had a good experience with TGA!

Worst customer service around do not go here!!!!

Great Subaru shop
