Just how rich does this engine run stock..?
 

I know this puppy runs rich during WOT. I can smell it when I go WOT,
say getting on the highway.. My MPG is good so it cant be too bad and
no odors during "normal" operation.
My last car did this too.. the OEM keeps EGT's down by dumping fuel during
WOT.. I dont think there is a problem.. other than the stock programming.. I was curious as to how rich..

Much the same as any other modern cat-equipped car. Above a certain point it'll taper down to whatever is necessary to maintain exhaust valve and cat temperature. Touching lambda 0.75 at the redline is not uncommon.
