May I suggest the driver mod? I'm close the next time you have an SRT-8 in your hands you want to track test .

Seriously though if it doesn't run the number obviously something's wrong. You should've stuck it on the dyno with some flow meters (air flow and maybe fuel flow if possible) and gone at it.

If it's burning that much oil I'd expect quite a bit of detonation, possibly pulling tons of timing and maybe even throttle. Did you ever think to check throttle position? You know these things are drive by wire...
