If your looking to get that LS engine running at peak performance Jeff is definitely your guy. Very knowledgeable and excellent at what he does. He is the only guy I go to and highly recommend.

Excellent service and very knowledgeable about GM Performance and LS tuning. Very responsive to questions and makes suggestions on how to improve your vehicle. Heintz Racing is the only shop I trust with my 9 second Camaro.

Outstanding shop. Only guys Id let anywhere near my Corvette. Jeff and Corey are approachable, knowledgeable and do top quality work.

Great knowledgeable people that know what there doing when it comes to performance ...they built my 03 vette..

These guys are at the top of the food chain they know what theyre doing they are awesome bad a$$!!

Very helpful guys & surprisingly they had every part in stock I needed for my old school 454 Thanks guys! Ill definitely do business with you all again.

These guys rock. I had a C7 that I wanted to upgrade, but only had a limited budget. Jeff and crew came up with a great solution for a budget friendly price. 10/10 would reco.

Called to ask about tuning prices, when I told them what I was tuning they immediately hung up without another word. How rude.

These guys are awesome!

Very nice guy excellent work

Jeff does amazing work. Could not have been happier with the car.

My buddy works there. Hell yeah
