I am tuning my 2008 silverado automatic 5.3. I have deleted i belive all the tourque managment i can find and i am working on the shift firmness now. There are like 10 tables for shift properties though. I want it to shift hard on the 1-2 and a firmer than stock 2-3 but i cant figure it out. Is it one table i am missing or is there a few i need to play with? any help would be appreciated. also if anyone has a good scanner config for these trucks please let me know. i am trying to piece one together
