2008 Chevy 3500 installed EFI live tune now on every start you have to stay in throttle to clear out then runs good until next start any ideas or help would be appreciated
Who wrote the tune? Did the condition exist before installing the new tune? Does it still exist if you put the tune back to stock programming?
If the condition started after you loaded the tune, and goes away when you go back to stock programming, then your tune needs work.
EFI live does not write tunes, it is a program that allows this to be done. You need to go back to where you purchased the stuff and have them fix it.Condition did not exist before tune EFI live wrote the tune in with the V3 once you install it it deletes all other tunes can’t go back to stock
Need to talk to your tuner where you got it. Let them know the issues and they'll adjust the tune accordingly if need. And x2, always save your stock tune! You can get it bench flashed at a dealer for reasonable to put it back to stock though. Then next time you read it, download your current tune and save it a few different places.
