Bought this to get rid of the AFM so far it is Great no delayed throttle response anymore. I have my truck set up for premium fuel it runs great like driving a different truck no comparison. Can't beat it for the price be careful when looking at other programmers this one has a lifetime warranty most others only have 1 year. That just tells me that this company stands behind there product.

Worked as advertised. My calculations say my tires are 34". With truck weight they measure about 33.5. That is the number I used and it put GPS spot on. Truck seems to be shifting back into 4 cal mode more regularly now helping to boast mpg. Worth the investment.
