High Performance Tuning

Performance In-Frame Tuning provides tuning and repair services for EFI-controlled systems only.
No traditional carburetor tuning or repair services.

A Family Matter

Performance In-Frame Tuning is a second generation Napa-native family business. We love cars and people who love cars. We repair cars for people and their family as we would want others to repair our own and our family's cars.

Sure, we're top notch mechanics, fabricators, and auto-electricians. But mainly we're relationship builders. We repair and improve cars for the people of our community. We are known both for great service and community support. Our great reputation is no accident.
