FSi Racing & Tuning

Nub was very good at tuning my Escalade! I would recommend him to anyone who would like to increase their power and fuel economy!

I have nothing but good things to say about Maysn and Tim. I’ve had my Firebird in their shop for various upgrades and came away happy and very satisfied every time. Maysn has worked on my Firebird for most of the 20 years I’ve owned it. FSI really knows their way around LsX motors of all sizes and levels of HP. I recently had them retune my Firebird on their Dyno and left with what I felt was the best tune I’ve ever had. (The previous tune was at a shop Maysn worked at but not by him). I wouldn’t trust my Firebird with anyone but Maysn and Tim. I’d give them 6 stars if I could.

Have had multiple vehicles here and will continue to bring these guys more business in the future. Extremely intelligent staff with meticulous work, from tuning, to engine rebuilds, to custom fabrication. If anyone is thinking about having a GM vehicle tuned, this is the place. In house dyno, thorough explanation of what the strategy is ongoing any work performed, as well as competitive pricing! I needed some Holley parts and was talking to them....come to find out they are a Holley dealer! Parts, labor, knowledge, cleanliness, organization....all top notch!
