The Hypertech Programmer help give the truck a nice lil bump in take off and pick up. I really liked the sale price i was able to get from AutoAnything.

I purchased this more to disable the fuel management program and recalibrate speedo for larger tires, but decided to do the full tune. I am very pleased with the outcome! The truck doesn't lunge while downshifting (because of AFM), it shifts smooth and confidently, performance is improved, gas mileage stayed about the same as w/ AFM, and it doesn't require 93 octane. Even w/ an exhaust system and cold air intake, the tune went smoothly and never any check engine lights. Very Happy!
