restored back to stock and CEL went away. Drove for an hour and it hasn't returned. If it was a hard failure of the CAT, O2 sensor or wiring it would still be throwing a CEL regardless of tune.

Going to leave it stock for a couple of weeks just to make sure.

BTW... I was on the "ract tune" since I got the tuner until now. I'll have to say its not a tune you want to keep on there for just around town driving. Shifts are pretty darn hard. I like it that way... but definately not a long term tune to leave on.
