I hope like hell that thing has 3.79's or 3.90's in it for that operation + your keeping the RPM's up at 1600 when pulling. Otherwise, I see you re-building that thing in 300-400k miles or so (far less if it has a bad/poorly written de-mandate in it).

cummins should have never put 2050 torque in the ISX the way they did, especially the newer ones with high compression like the 2350 or X15.. They only put that torque in them from the 1100-1300 RPM range where it completely tortures/beats the liners out of them.

If I owned it and needed to have high HP,.. I would lower the torque and raise the HP to something more usable in the higher RPM ranges where it needs to be.
