I'm looking for input on what the optimum tuning would be for this. It has 4.33 gearing and ten speed Eaton. Plan to run long haul. This is owned by me. Unlike the T700 I'm driving. It is a 1993 Volvo WIA. I can not do all work myself. But try to do what I can. Thinking on a pro link programmer or do I need software for much on DDEC 2?

honestly save yourself the time.

upgrade it to a 4 (detroit makes a kit and its easy) then go from there. it can be tuned however you like after that but the single biggest improvement is the 2 to 4 electronic system upgrade.

I'm thinking it's factory set at 365hp. But the gearing is awesome. Can pull anything at 60mph.
