I do this EVERY year, I will get my emissions done without messing with my fuel pressure (42psi daily) and I will only pass like half the tests. I then come back another day and turn the fuel pressure down ALL the way and it pasts every single time. I'm currently running a Magnaflow high-flow cat. Of course I still have all my emission devices too though.
