Superchips Flashcal Calibrator for GM Truck
Bought this for my Silverado 2500HD. After I purchased the tuner add on, it significantly increased my horsepower. Its a difference of night and day. I initially had a problem with configuration of the tuner. A couple phone calls to SuperChips tech support and it was fixed with 3 updates. Etrailer and SuperChips customer service is second to none. I will pay more for my purchases just for the peace of mind knowing a company always stands for their customers
Exactly what I ordered, for to me fast an I love everything about it
