i've tried pretty much everthing in the book to get rid of this with OS. no go. mine is either that code which means reading below thresh hold or the not dectecting it at all code. i came to the conclusion that since i'm running e85 i will see lower emissions no mater what so there is nothing i can do to "pollute" my air so it will read above the thresh hold

Try putting a bit of steel wool within the spacer. It's a delicate balance to get just the right amount of exhaust hitting the sensor, but this has been effective in many cases!
You need to block a bit more from hitting the sensor, so a bit of steel wool should do the trick.

I don't think so. I have a TurboXS full turbo back with test pipe. I initially threw the code, but then it went off. I'm on my 3rd tank and still no light or code. I'm on the stock tune.
