Tag along with us while we replace the ECM on this brand new 2024 Ram 3500 6.7 Cummins so we can dyno tune it with HPTuners. We started off with 375hp/994tq all stock and ended up with 449hp/1087tq. Dyno tuning to be continued once we have access to more info in the data logger software and the shift on the fly operating system is released by HPT for the 2024! In the mean time this fella gets to enjoy a gain of 74hp and 93ft/lbs of torque, increased engine speed & removed speed limiter!
