I have mine in the Y. been there for years and no funny reading. It was .3 differance on the dyno wide band. iTs also a AEM. I also had it after the turbo and it work ok.

didn't do it with the stock cam but when I added a cam my readings starting jumping around, added a piece of exhaust hose and the readings smoothed out. Moved the sensor to the I pipe and all is good.

So your wideband O2 sensor sits 2" from the exhaust tip?

When you say "I" pipe do you mean after the duals come together? sorry for the retard question. I was reading that most put it on the drivers side....or maybe it was on the passenger side....which ever one was because one bank ran leaner than the other. I am all ready to drill but i was hoping that more people were running theirs before the turbo.

was wondering, on the rear mount widebad o2, does it matter if its 2" after thr turbine or 14" ? reason i ask is that im getting a resonator with an 02 bung on it and depending on the orientation puts the bung at either of the distances mentioned above.

the reason they say this is due to the fact that oxygen sensors don't like pressure. above a few psi they will rail out, meaning go to a 18:1 AFR reading.

in a rear mount, depending on your pressure ratio and turbine, your exhaust from the block TO the turbo can be a few psi. this will cause them to do funny stuff.

at the outlet of the turbo it is just slight positive pressure, especially if you don't have a long exhaust run.
I put my wideband 8 inches after the V-band at the turbo outlet

unless you have ECM wideband , you need to mount it after the turbo .
