Does anyone know of any tuning options for an industrial 01 5.9L ISB with a VP44 in an F650?

It’s currently rated at 225. CPL 2685 Manual trans.

The truck weighs 14k empty and pulls an 8,000lb chipper 100% of the time—gross weight 23-35k.

Mostly local driving with some highway, but the street isn’t the issue.

Long term, I’d like to put a P7100 in it, but anything in the meantime would be significant.

The biggest thing is where the powerband is concerning the gearing.

Turbo doesn’t start spooling until about 21-2200 rpm, which means you are dropping out of boost every shift for 2-400 rpm.

(Governed just over 2500) If the timing and fuel onset could be dropped a little, that would increase the drivability exponentially.

Our 12v’s develop their boost significantly earlier.

Has anyone has any experience with these?

Most places I’ve looked at say Dodge only software.
