How does everyone know it's his upstream sensor when he didn't even tell us what his plugs are gapped at?!?!?! How do we know they are not gapped at like .38+... Let's not go throwing parts around to try and trouble shoot a problem... Let's start with the basics here folks...

19psi on stock turbo might cause some issues, but not on stg3. I and many others are running 25-26psi on stg3 with no issues. What plugs are you using and are they gapped around .032 ?

Get rid of the .038 gap... Gap it down to .030
