Excellent service and knowledge I would never let anyone else touch my car.

Go to shop, they are happy to work on my LS swapped e30 BMW without hesitation and are always informative and helpful. Got a tune for my car today and couldn’t be happier. Great prices and quality service.

Great experience at DDP - the guys work great as a team, understand the clients goals, and share their expertise freely.

This is a great place to take your muscle car or hot rod for tuning. Its a family-owned and operated business and they take pride in what they do. Good job guys.

If you need any work or dyno. These guys are the best ! Nice great work and price cant beat it. They have so much experience and do the work themselves. Hard to find guys like that . If you have an old school dont look any further

I just had my Porsche 911 race car dynod here. These guys are knowledgeable, professional, and a joy to deal with. No affiliation, just a very satisfied customer.

These guys are 100% legit.

DDP is the best old-school tuner in the Bay Area. You wont find anyone more qualified to work with a carbureted engine. With their dyno and tuning abilities these guys can make cars do some pretty amazing things.In general, Vic very quick at his work and has diagnosed many problems that other mechanics have failed to find.

Top notch.guys that know there s#it !

Great Tuner!
