Yeah but....the Cummins doesn't hit max HP until 2800. Torque max is 1900.

My 3.42 tows great with 6th locked out.
Max torque is at 1700 RPMs. Chris
And this Max torque at 1,700 RPM is at Wide Open Throttle (WOT).
People always forget this minor detail thinking they're going to get Max torque driving this RPM down the highway. Doesn't happen unless your running WOT. The same applies to HP.
And in normal driving it will mostly shift down to a lower gear before you reach max torque or will be at max torque for only a few seconds before it shifts down. Chris
