Best Superchip
This is the best superchip that I ever experience.Yes it does give you more Gas saving and power. It's responds faster and everything. I bought it for my GMC 2002 4x4 5.3L.

Great Addition
Easy to install with minimal tools, plug n play performance. Boosted horsepower and improved mileage in my Tacoma by 5 mpg with exhaust system and programmer.
