Can You Dial Up HP On A Cummins Engine

565 was the Gen I tune which was labeled 580 on the Gen II.

There is a higher tune, which is the higher TQ 600(gen I)/620 (Gen II). 2050lb tq.

But the real appeal ( for me anyway ) is the rapid TQ rise, full Tq by 1200 iirc..

 

yep had a couple n-14 330 if you lucky it will up rate to 430 and 1450lb of torque, day light and dark

my other one they would only take it up to 350 and 1450lb of torque still was very weak so I swaped ECM from a 370 that was cranked to 460 and 1650lb, that was the strongest pulling N-14 I have ever had,

 

the 06 isxs never had a factory 2050 ft.lb torque rating there is a 600 hp cal. but it is for rv use

 

Never understood why they gave the old man in the RV the big power. You don't need the hp when your always doing 45 in the right lane.

 

I dont get it either
But it is VERY interesting how top, 600hp rating was dropped in 2002 due to problem complying with new emissions - but RV were still getting 650hp...

 

It is:
Apr.2000 ISM-350
CPL2608
Service Model Name- ISM CM570
Fuell pump # 3417674


what can be achieved w/out loosing reliability?


p.s. My appology to OP for highjacking thred

 

Look abroad.

The next level of tune would be the 620/2050, which you guys may not have been offered, Yet we have it.

 

I have thought about that, I think you could have yourself a nice side business shipping ECM's to us EPA castrated engine owners.

 

With our dollar so high, it wouldnt be worth it, as our parts are pretty #### pricey.

Its also hard to get an ecu seperated from a motor in the wreckers. thet almost always only sell as complete units.

 

I'll double check tomorrow, but that CPL I think can go to a factory 425V rating.

You could certainly go above the factory rating without loosing reliability but it's up to you as the driver to keep it alive when it's gone beyond the OEM rating.
