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!

Works very well took existing edge juice with attitude out and replaced with bully dog. I forgot how much was involved with my edge all plugs and harnesses. Much cleaner install and now I can calibrate my factory speedo instead of looking at tuner screen for speed.
