Oh my gosh. This thing is bad ass! Made my truck a lot quicker right after I put it in. I'm getting 16+ MPG with 35s and made it start spinning when I punched it at 45! What are you waiting for? Buy this tuner!!! You will not be disappointed! Also, always pleased with AutoAnything!

I noticed an annoying exhaust note change when the AFM would kick in. The range device corrected that problem instantly. Product seems to well constructed of solid materials. I haven't had a chance to check any mileage changes but at this point I am satisfied to have the engine at full power. The truck is more responsive to the throttle.
