[QUOTE="biturbomg, post: 1368558, member: 22257"] Has anyone had any issues with the MPT tune with or without the trans tune going into limp mode when sport mode is engaged? My truck runs great in normal mode, shifts fine etc. With the trans tune the shifts are a bit rough but nothing crazy. I learned though when I put it into sport the truck throws a CEL and has misfires and goes into limp mode every time. I took to dealer to look at the truck and they couldn't find any issues and without the tune sport mode works as it should no issues, load the tune and go to sport and misfires again and truck goes into limp mode. I talked to MPT and they blamed the spark plugs or coil packs which makes no sense since it is fine in normal mode tuned and fine in sport and normal mode when not tuned. I have lost some faith with MPT and thinking to try out Cobb as they have done great on my Porsches and GTRs. Can someone explain what happens when the truck goes into sport that would cause misfires? Thanks for any help. [/QUOTE]
