I’m trying to “turn up” my ISX and I was told This is the place to ask.

Shops around me won’t touch it because of emissions. I’m not trying to mess with emissions just looking for a little more power. Finally they Dealer said they could to it but after further research Cummins told them there is no available update/tune for my engine “because it was a very specific built engine.” Guy at the dealer said he’s never seen or heard of something like this. They were willing to do the tune of Cummins would provide it. I was wondering if anyone else has had this issue? Sorry for the ignorance I come from older cats and detroits.

Info given to me from dealer….


2004 signature series Cm870

Serial # 79052701

Thanks,. It already has the bigger HP injectors in it for 550HP. As long as you are not going to heavy-haul with it, can go to about 1790 trq and 535HP easily with no loss in longevity.

Someone just needs to take the factory 'AB10423' program and adjust the HP/torque to what is desired on it before flashing it in.

It is a run of the mill CPL 8520 engine. Noting special about it other than the cams need to be set a 6/6 offset rather than 4/6 during an inframe. It is quite common of an engine and is not 'special'.

Yours is also a a typical 2-engine brake solenoid engine, so it needs a compitable program as such.

As far as standard programs from cummins goes that any stealers$it can flash into it, a compare of the more than 6,800+ settings in the program reveals that ...

* Program AB10525 (500HP, 1650Trq) is 100% compitable with your ser# engine.

* Program AB10487 (450HP, 1750Trq) is also 100% compatible with your ser# engine.
