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.

As my title states, it's a good product and calibrated my speedo since I put 35's on. The only reason I give it 4/5 starts instead of 5/5 is because I had to put 33's in the programmer to calibrate my speedo correctly. When I put 35's and went for a drive, my speedo read 70mph when I was barely doing 60mph, what the heck? So I had to calibrate my truck about 4 times to get it dead on which was a bit annoying, but it eventually worked. Worth the $200 for me, I can't stand my speedo being off!
