[QUOTE="97cherokee, post: 1552158, member: 22488"] so i have a 14 6.7 that intermittently has issues with building boost, i have converted it too a 2015 turbo setup, it was doing this intermittently as well with the old turbo. so what it is doing is i can crank the truck up cold, run 5 minutes too the gas station, shut it off. come back out and leave and it wont build any boost, black smoking (******d with proven diesel tunes) did it with the old turbo and stock ****** hs tunes as well. any how get going a bit, mash the throttle a few times and itll start building boost fine and typically be fine for the rest of the drive, although sometimes itll quit building boost while driving. im not having a cel pop up at all. truck has a new exh gas psi sensor at the time of turbo change, newer boost psi sensor and newer map sensor as well. thanks for the input!
