2023 camaro ss 1LE
Fsi has taken my camaro from bone stock to full exhaust/heads/cam/intake manifold/e85 taking my car to the next level! The mechanics there knocked it out of the park and not just with the performance but the tuning for drive-ability and DEPENDABILITY! Mason, Nubz and the guys there did a masterclass job. Very pleased with the numbers! I picked the car up on a Thursday, then Sunday headed down to Indy for the hotrod power tour and drove just over 1000 miles for the next 5 days, ZERO issues period! Highly recommend!
