It’s not just the PCM. It’s the BCM, TCM, and ABS as well. A late model trans and engine swap is much friendlier with aftermarket controllers and harness. Heck if you build a late model Challenger, Charger, etc.. You have to source a separate controller just to run the windows up and down if not using a factory harness and BCM.

Thanks Doug , I'll have to do a gear swap then so the RPM is higher .

Question since you worked with this stuff , can the DRB tool adjust the MPH point I want to change ?

running up my post count some more .
