I Installed The Non Foulers In My Test Pipes Then Reset The Ecu Using The Key/gas Pedal Method. Light Went Off And Came Back On After 28 Miles. Could It Be The Oil From The Filter Off Of The Popcharger Collecting On The Maf?

 

How big of a bit did u drill the non-foulers? Too much and itll run dirty. Too little and itll run lean. I think u did too much. ( >.5inch )

 

I used a 1/2 in bit

 

If the O2 sensors were still covered, that could be your cause.

 

Did u put 2 nonfoulers on top of each other?

It should be (from outside in..)
O2 bung --> Drilled non-fouler --> non-drilled non-fouler --> test pipe
