Just put my wait4me PCM in. I have to do a relearn no biggy. I am happy so far. I am going to do the Crank Relearn. The I will go to the track and compare stock PCM to the wait4me PCM. Jesse hit the shift points perfectly. Its hard to tell a gain in power because of my elevation, but the truck runs stronger. Still cant break loose the tires no matter what. Damn it sucks being at 4k feet ASL. The 3.42s probably dont help. Anyways I will keep ya posted.

Yea, the right scan tool or a GM TechII is needed. I went to a local dealership to have mine done, they charged me .5 labor (about $46).
