Could someone fill me in on wide band o2's. Are they just used on dynos? Do people use them in their car? I have read their very accurate, but also heard their price is heavy. I just need to be filled in on wide band o2's. I'm going to be running 450-500hp next year and I know nothing about wide band o2's. ignorance is bliss and a recipe for disaster.   thanks all, Kevin 88 red esi-r 88 purple tsi
