    2bar OS upgrade only with 14+PSI? Or swap pcm's

    Getting ready to ditch my cammed 6.0 swap for a stock 4.8 with boost. My pcm only allows 2bar os upgrade. Questions are what are people doing to run higher boost than 14psi on this OS?

    Other option if there isn't an easy fix is to swap pcm's with my buddies truck that allows 3bar OS.

    Just wondering before I copy and paste everything from one file to the other to swap pcm's or stick with my original pcm.

    I think and ecu swap is in order, or go full aftermarket EFI.
