Well, I decided to make a few changes and make my first write to the PCM! Here's some screen shots of the changes.

Vehicle specs are: 2007 GMC Sierra Denali, 6.2l L92, 6L80E, 3.42s...everything is stock.



I disabled all of the TM master switches for the trans.





and I lowered the PE Delay RPM from 5000 to 0 and raised the PE enrich rate from 0.05 to 2.0 (Suggestion from HPTs forum).





and I also zeroed out the A/C torque reduction table





It pulls a lot harder now and it doesn't seem to fall flat on it's face near as bad between shifts either. Am I on the right track? What other changes should I make?
