The folks at GPI are both professional and very knowledgeable. I was treated fairly. All my questions were answered to my satisfaction. They will treat your baby as if it was their own. I was briefed every step of the way. It is apparent the fine men there are dedicated to satisfying the customer.

These guys tuned my 2016 Sierra and after having it for about two days now, I absolutely love how it changed this truck. Better fuel economy, none of that sluggish GM shift points. 10/10 in my books and A+ customer service, I would trust these guys with any performance work that you need.

Bought their ported/rod modded intake manifold for my 2010 Camaro SS L99 and holy crap, it's amazing! The porting looked well done and I am very impressed!

Great customer service. Been bothering Dan for 3 days asking many questions, some over and over again, and he answered all of them like an expert. Bought 3.91 gears from them yesterday and will be going back shortly for a cam. Appreciate it fellas!
