So I called tech support with the issues I've been having, and their recomendation is for me to send them my program and they will give me a custom program that will allow for the speed limiter to be removed, change my shift points, correct my speedometer and not have my dash lights go off... This ...

Okay I corrected my tire size & it made it worse.. not only did the ((!)) and (ABS) lights come on my speedo was now 5% high... And the main reason I got this thing was to get 2nd gear at WOT up 110km/hr.. this P.O.S. didn't change that...any suggestions or should I just try a different manufacturer

I just purchased one for my '07 5.3l, was really surprised that the speed limiter was still on.. when I removed it my ((!)) and ABS light came on.. add the limiter back on and the lights go away... I'll try the tire size adjustment.. but really I'm not going to drive around with lights on my dash ...
