What all changes in the PCM is needed to change from DBC to DBW? Donor vehicle was the 2006 Exporess Van 4.8/4L80e DBC... Was told the DBW is an option with just some PCM modifications.

There's a thread I've read somewhere on the performancetruck.net that shows what to look for on the ECU. IIRC, some ECUs actually have the drivers for either...I think you pop the cover off the ECU.

If you verify that it has the driver, then it's a simple check and reflash via HP Tuners, etc.
