However, those very same turbos hurt the PSD in other areas like exhaust breaking which is something I use all the time.
Although just adding a plug in play BD throttle booster without a tuner made the Cummins feel just as spirited off the line and in normal driving. Add a tune or module, and there is no comparison.

The odds of a Cummins failing in the 100k mile warranty period is slim to none.
