Dyno'd at Cummins with their latest calibration 650HP to the wheels 1850RPM
and 600HP@2100RPM with 2200TQ. Almost 1 mil miles still before inframe. It's done it's duty to the west coast. Now it's doing south east. No plans on swapping the Holset VGT and going non wastegated. Cummins interbrake with VGT FTW!
