atmospheric Bypass valve
When I bought the car, it all ready had the atmospheric bypass on it. Yesterday I got the code p2261. Now I have found forms saying to by pass the solenoid, and none have photos.
Also, several have said that the car needs to be tuned for it. The car had a trifecta tune. Last weekend I swap out the ECM with one from ZZP. When I order it I did mention it had an external blow off. Is there a chance the swap could of caused this?

Well I switch ECM back and after a couple hundred miles no code. So I am assuming it's the tune. The MAF is in the stock location. Can I move it to the intercooler pipe with out a tune?

what spring are you running? I ran the yellow spring for about ~1 year on MAF tune and the car ran fine. I know Term had to mess with some **** to get it to run ok. I ended up getting p0101 multiple times so I relocated the MAF.
