Also tuning my truck
09 Silverado 4.8
I have added 4.11 gears
I have removed all TM (i think) and have moved the high spark table to the low and smoothed out. I am still reading up on other things. So its a big learning curve.
The truck really does feel so much better now. I feel it is so much smoother.
Anyway lets try to make this a tips and tricks of what works and what doesn't, I know I need all the help I can get!!!!!
