Leroy has done a lot of work on my car and never has any issues. He put on an ECS supercharger 2 years ago with a tune. Worked great. This year I upgraded to an AGP 4” intercooler and new tune. Car runs amazingly with stock cam, heads & converter. The turn around time is always great. I am planning on doing a large amount of work to my car later this year including cam, DOD delete & heads. Leroy and Joe do awesome work and never oversell & walk you through what they did.
