I just got my apr chip changed to stg 2+(to eliminate the cel since im running test pipes). well after i got it back there was still a cel, so i plugged the vag in and it said rear o2 sensor bad no reading. i talked to a buddy and he said the stg 2+ chip does not eliminate the rear o2 sensors, it just eliminates the difference in readings from the front and rear o2s.

so my question to you guys is should i just buy a new set of rear o2s or should i try the non-fouler option?
