I have a question about my wideband gauge, im thinking its on its way out but im not sure, my a/f ratio is all over the place at cruise, dead lean or around 12.0 12.5 sometimes going to 14.5. wot is 10.0 10.5. if it wasw going that lean during cruise wouldnt i get a lean code. can it be something in my tune?

The best advice I have ever heard:... Only take B( . Y . )ST advice from someone that is CURRENTLY running a turbo setup close to, or bigger than what you want......
I have the sensor in my rear o2 spot. how bad is the cat throwing off what the gauge reads?

The more bad news is your better off before the cat then after.. the cat will superheat the exhaust and Kill the sensor well before its time .... I would at least move it upstream...Originally Posted by blown 04
