PSI is a small, passionate team of car enthusiasts. Based in Carmel, Indiana. Our goal is to help you hit your performance goals, without charging the obnoxious markup most shops have.

We prefer to work closely, and directly with the customer, inviting you to see the work being done, you may be as involved in the process as you’d like.

At the end of the day, we are all passionate about the same thing...

Speed, over everything.
