Hey guys new to this stuff and Iam trying to do just a basic tune for a 05 4.8 crew cab 4l60e I drive daily . I was trying to use the BC tool but I am obviously doing something wrong because when I put in my tire size of 31.9 275 55 20 it?s asking to shift WOT wayyy high . Any help would be greatly appreciated.
Just realized the photo didn?t upload working on trying to get it to post
But it’s asking 1-2 54mph and 2-3 102mph 100% throttle
