My tune issue is this. Currently I run two different tunes that work absolutely perfect. A third tune that I attempt to run “a race tune” will not let my truck run properly. I believe it goes into limp mode either right at start up or when I have been driving for 3-5 minutes. The truck just starts sputtering, blows a bit of white smoke and has absolutely no go power. I may get 5 mph out of her when she is acting up.
Does this sound like limp mode and is there anyone who would like to take a look at the tune to help me diagnose the problem. I need more qualified eyes.
