Power Programmer By Hypertech

I have a 2003 Avalanche Z71 and i used the hypertech power programmer, What a World of Difference!!!!! I was able to raise my Max RPM which was 5600 i bumped it up to 6000 to keep it within the tach range I also adjust the shift pattern and the firmness of shift, The Truck Now has a Definiate Burst of power and the raise in Shift points and RPM helped it Alot!! I reccomend this for all

Check out the other threads in this section....lots more power to be gained

Have we ever really come up with the peek settings for 2002 4.10 rear I did find the other threads great. How was the turn out to date with everyones settings?
