I never went that route, but back in 05 or so I met someone with one of them in Moab. They liked it alot.
Tuning was pretty limited back then. Now you could tune it much better.
So the rolling chassis came with a programmed ECM to mate with the Avenger but, the ‘02 tub and PCM got locked out when we tried to mate them. Installed ‘02 ECM and are still locked out.
Gonna try to reset the PCM with a “drain” method but this may require a phone call to Mark @Wranglerfix
We will see.
