[QUOTE="John v, post: 1562802, member: 37538"] Having a similar issue. My 08 6.4 350 was blowing white smoke. Changed fuel injectors and both turbos. Went to drive and transmission started to not shift properly and would give a hard kick. Changed the transmission and now the truck starts and runs good half the time and blows no smoke but when I take off it starts to putt putt and blows white smoke when it does. It has H&s tuner and when it starts to run rough the Tuner goes sporadically jumping all over. We are thinking it’s the PCM after all of that but I’m lost and need help. Had diagnostic ran on a $15k computer and the PCM wasn’t responding. Don’t know if it’s throwing my injectors off or what but when it starts It sounds good and runs fine. When I take off it doesn’t have the power it should have and starts putting here n there. [/QUOTE]
