I am a ram 1500 owner glad to be part of your forum. i own a Diablo p2 tuner today I accidentally change the tire size. I know Duh. but what happens now is i roll about 20' and it auto shifts into park. The truck shifted fine before that. I have reset the program back to factor tune but the issue still exists. I have gone back into the tire options but the tire size numbers do not make sense. it shows 165 will go down but not up and when i try to reset to stock is says it fails. Has anyone had this issue before?
