well fellas, i knew i was gonna fail....why? because the ecu IS indeed chipped by the Mugen prog...

BUT, my question now is, can that ECU, ALONE cause all those high numbers in both HO and CO ?

and you bet i tried frying that cat, the trip to ESCONDIDO from the middle of SD is like 30 minutes

i guess i'll just have to research on the net about what causes those high numbers, the cat is fine, had it recently replaced from a muffler shop, and yes i have the correct 02 sensor on it as well....

Thanks for the replies fellas
