Hello All,
I got a 2004 Silverado 1500 with a 4.8 and a 4l60e. The computer calibration is 12585950. The attached tune is what I pulled out of my truck and Im worried it isnt quite right... It says its for a 4l80e. I just put a rebuilt transmission in the truck and it doesnt feel quite right (500hp monster performance transmission with 2200rpm torque converter). Any advice on what changes I should make to get it right?
It should be noted idk what previous work was done on the truck but I got it from a shady dealership.
Many Thanks,
Michael Scott
