Ha thats funny Cummins detune the ISB for P/U truck use the horsepower limits of the 5.9 is pushing it now for maximum reliability. Cummins sure has you brainwashed the ISB started out a 160hp the marine version at 370hp isn't constant duty thats pleasure craft rating. If the Cummins ran at that power all day and everyday it would last less than a year myself I don't believe that the ISB is what Cummins claims it tobe. Its a crock of **** that Cummins claims the ISB is a medium duty truck engine you put that in a 5 ton truck is barely adequate.
Thats interesting, where did this info come from?

BTW whos brain washed?

Whats this post mean?
