Very satisfied. The Hypertech Speedometer Calibrator arrived quickly and was very easy to use. The instructions were clear and walked me through the programming process smoothly. I tracked my speedometer accuracy with my GPS and before calibrating it it was off 15%, which meant I was traveling 69 mph when my speedometer dispayed 60 mph. After programming with the Hypertech, the speedometer is spot-on. I can also easily reprogram when I install my smaller diameter winter tires.
Great Programmer: Will disable AFM!

I bought this to turn off the AFM (Active Fuel Management). This fit the bill and then some. I want to tinker around with the other options later. If you want to turn off AFM, buy this one. This was the only one that I found on this site that will do this. I originally bought a Diablo programmer and found out after I got it that it would not turn off AFM. I was able to return it and get the Hypertech at a reduced price. Very pleased
