07 Peterbilt. I took a six 870 out and put in 09 isx 871. Will my 870 ECM run the 871?

If its demandated and you use the air actuated turbo off of the 870. You'll need a bit of custom programming.

Yes it's demandated. Swapped turbo off the 870. It runs but the roms and torque are different. What tuning would it need?
