For a TT set-up, should the o2 sensors be mounted before the turbo (intet) or aftr the turbo (down-pipe side)? Does it really matter? Any advantage of either locacation?
How would the reading be skewed? Does the o2 content really change that much when ran thru the turbine? Hmmmmm......I'm new at all of this, so please shed some light on the subject.
