2013 6.7 that I'm having trouble with the throttle being jumpy right off idle. If I monitor throttle position it goes smoothly from 1-100. If I monitor boost it goes smoothly from 0-26ish. If I monitor exhaust back pressure it goes from 0-1-2 but then jumps to 6 or 7 and is then smooth on up. The issue occurs just before I see the EBP jump from 2-6. Also when you monitor boost vs back pressure they are very relative to each other aside from when its doing as described above.
Possible bad back pressure sensor? Truck did this stock but much worse now that it's tuned/d-leted.
