Afternoon everyone! I just un-installed a programmer off my 04' 6.0 F350. Now truck will start, lobes hard and dies!Ran fine before I removed it. Also notice oil coming out exhaust. Anyone have any ideas? Could the programmer caused an issue? I tried re-programming and starting, did the same thing. Thanks!

programmer can hide some problem or make them worst. I'm not familiar with the 6.0 but I would definitely try to get the truck run perfect before reinstalling the tuner. Probably someone with more 6.0 knowledge will jump in

Programmers can and will hide alot of the problems you will encounter on the 6.0. My 6.0 had a bad injector, and a weak hpop but you could hardly tell with my SCT race tune. Do you have white smoke coming out tailpipe as well? Sounds like maybe you have a bad turbo, or injector(s).

Oil out the tailpipe sure sounds like a bad turbo but I wouldn't expect that to be related to your idling issue.
