supercharger emission testing

[Tone]

They have passed in CA with aftermarket exhausts many times and for intial certification. Might want to clear codes before taking it in...or fix the problem - it is not the supercharger or the exhaust. Intial CARB testing and certification was done with stock airbox in place.

That particular series of codes usually sets only during high vacuum decelleration, you probably can clear the code just before testing and test clear. Then you will be able to solve the reason without being under the gun.

You can borrow my scantool.

Personally, I would start with new intake gaskets, check to make sure the fuel pressure regulator modification was done properly, and try again. (Yes, the S/C has to come off again for this). This seems to be the more likely culprit than sensors, injectors, etc.

Anyone else have better insight? (Agree/ Disagree?)

What you're experiencing sounds similiar to the problems I had before I replaced my intake gaskets.
