AMS Performance

At AMS we specialize in automotive performance for Japanese and German turbocharged vehicles. We offer engine computer tuning (calibration), repairs and maintenance and most importantly engine and other driveline modifications.

First and foremost AMS is an engineering company. Unlike other shops our parts are engineered to be the best performing you can buy. Most shops in the industry have a basic understanding of engine performance but at AMS we take it far past that using computer aided designs and mechanical engineers with years of motorsports experience.

AMS and its sister brand Alpha Performance have been at the top of the game for 15 years. From turn-key packages to individual components we can meet and exceed all kinds of performance goals. From drag racing to road racing to spirited driving on the streets, let AMS enhance your driving experience!

We offer extreme turbo builds all the way down to simple tuning upgrades.
