Tuned a few of my cars here, cars drove off the dyno driving 100 times better. Ghayth is the man behind the computer, definitely recommend him for any of your tuning needs! Very satisfied

This was the only place within a 100 mile radius of my home that could calibrate my Mustang’s speedometer for 4.10 gears for a reasonable price. Ghayth is an excellent tuner and you can tell by the other cars in the lot that he knows what he's doing. Would definitely come here again.

Ghayth (Guy'th) was incredibly fair, incredibly knowledge, and incredibly helpful. Coming back here for sure!!
