i threw a code yesterday and it keeps coming back, it is p2270, O2 Sensor Stuck Lean-Bank 1, Sensor 2. i have a zzp downpipe with a high flow cat, do you think that adding boost started messing with the rear o2 sensor? should i have vince make me another tune and turn off the rear sensor? im just not sure what caused this code to come up after being on for 5k miles without any problems. thanks

I'd just delete the rear 02, that's the one after the cat right?

yeah. im thinking that the sc is just pushing more air past it and it finally started picking up the high flow cat

makes sense to me, if it's not a necessary 02 sensor then there's no point in dealing with the hassle anyways.
