Questions of CA SMOG test?

[NewBlueGT]

Just wondering...

If I lower my fuel pressure before the test will this help me pass emissions?

I have a Kirban FPR.

Just in case you read my sig, yes this car has passed twice in the past when I put on my original 4 cat H pipe.

It seems that ever year it gets to be more of a close call, so I do what I can before.

Might add in the SMOG PASS stuff into my tank before also.

But first, can I lower the Feul pressure? and to what level?

I will venture a stab and say that lowering the fuel pressure would not make much of difference. My reason being that, if your fuel pressure is high enough to fail you for CO, then it probably is high enough to take out your cat. And you would fail anyways. So, I would guess if your cats are still working then your fuel pressure is fine.

interesting....

Any other thoughts?
