finally got it to read, now I need to know what to do. I tweaked a coupe things, but Im not sure HOW to change line pressure and other things. Its a stock 2010 Silverado with 4.3.
I mostly wanted to tweak it to run my 22 inch rims in the summer and switch back to stock for winter.
I plan to add a CAI and exhaust but mostly looking for mileage and throttle response improvements. especially at hwy speeds its a dog when you try to pass.
here is my history log.Main File : 2010Silverado4.3summer.hpt

Pretty sure these use the same T42 tcm as the v8 trucks, you might want to ask in the v8 trans section as well as post your file there.
