My coach is a '13 with the 360/800 6.7 ISB that uses DEF, the trans is the 3000. Are there any power upgrades available for this particular engine without compromising it's integrity? I am aware it has limitations and has been engineered to be reliable. Seems as though I have read somewhere that some guys from Cummins tuned a few of them closer to 425/1000.

I also have no desire to delete the emission systems.

Are these claims malarkey or is there some truth to it?

Engine can be easily programmed for more HP & Torque.....but can transmission/u-joints etc handle the increases????

It appears that your 360/800 is the max rating from Cummings for the ISB. I'm sure that the after market tuners whose customers are the pickup truck owners push it up. These ISBs in a pick up aren't loaded to the same degree as in a 26-30k pound motorhome. It all adds more fuel & heat for a relatively small increase in performance. I would stick with stock as the choice for reliability.

The 425/1000 level you quote would put it up over the ISC hp level and approaching the ISLs 450 hp. These are considerable larger engines.
