^^^You can call it programming or whatever but it comes down to power. I don't know what grade the hill was that he was pulling but to pull a 14,000 lb trailer up a steep hill at 110 kph takes a lot of power. He was comparing a 385 HP Ram to a 500 HP Ford.... and he says it didn't pull as well on account of the 6 speed transmission,:S.
OK, explain why he had only 22psi boost?
I think he said 24 psi boost at one point. At 2000 rpm the standard output Cummins is not tuned to produce a whole lot of torque ….. no more than the 850 lbft peak torque it makes at 1800 rpm. Does the Cummins need more than 24 psi boost to make 320 hp at 2000 rpm?
The thing is the standard output Cummins is only able to produce about 320 Hp at 2000 rpm and he’s comparing that to a high output Powerstroke that should be able to produce about 420 Hp at 1900 rpm.
