Cm871 ecm tuning

[truckhead]

I need a good tune for my isx cm871 it a 525 hp 1850 torque engine. I bought that engine from a crashed 2009 kenworth did a complete overhaul on it in my driveway and put it in my 2002 freightliner Columbia. The issue I am having I used the cm570 ecm that my pervious engine used but that he was set too 500 hp 1650 torque. The engine ran fine until recently that ecm died it was the original ecm to the truck too so I don't feel bad. I have rewired the harness back to cm871 however my truck didn't have all the mandated stuff on it so I need to tune the cm871 to ran properly with the vgt turbo without having to add all the stuff on the engine
