07 5.9 Cummins. With a healthy tune, I can race past 14-1500 deg pre turbo on steep grades at highway speeds. Truck keeps accelerating as fast as the egt guage.
with a tow tune I can top 1400 as well towing uphill highway speeds.
I keep it between 1300 and 1400 though unless necessary to drop the hammer for a short period of time.
