A good friend of mine has a 6.7 cummins with the 6.7 and had a RACE.ME programmer on the truck. he asked me if id retune it because the tuner he is using only has the precalibrated box tunes and he wanted a custom tune. after restoring the truck to stock tune i was able to read the original file from the truck. i began to make changes until we had a strong file and truck pulls hard, egt look good and no smoke at full throttle just a slight haze. his truck has full deletes egr cooler, egr, and dpf. i have sense disabled the codes that are set for missing hardware but the truck still trys to go threw a regen cycle. At this point im assuming hp tuners doesnt have the ability to completely disable these systems. im also having a small issue holding boost up top too. no matter what i change peak boost goes from 30-31 psi to 27ish after about 2600 rpm. truck is stock fueling and stock vgt turbo original and modded file attached if anyone has any ideas possibly too much exhaust manifold pressure and the turbo is opening up the hot side more to flow? the logger for this truck kinda sucks too only logging very basic info. any input would be greatly appreciated
