Jesse posted on fullsizechevy forums on how to do it. Its in the 100$ tune thread. I would link it for you but that thread is probably very long now and I can't search. I wanna say it was around page 10 but don't quote me.

My service manual says to enable the Crankshaft Position System Variation Learn Procedure with the engine in operating temperature, the truck in park or neutral, and the scan tool connected...I'm assuming there's a prompt for it on the screen. Slowly raise the engine speed to 4000 RPM and immediately release the throttle when engine speed decreases. Turn off the ignition for 15 seconds after the learn procedure is completed successfully. (basically bounce it off the rev limiter)
**EDIT** You must first clear the code before performing the procedure...

The process that I have used is
Try to crank the truck... It will not fire leave the key in the off position for 11mins (no less, but more is ok)
Then turn the car off for 30 seconds (more is ok, but no less)
Repeat that 3 times... It will fire on the fourth...

yeah, mine seemed to shift really funny too, and it gave me some missfire codes high in the rpm range, do you think that will go away with the relearn? thanks for all your help
