Failed Smog! Hey guys, had my LT1 B-Body tested today and it failed. Anyone know what I can do to make it pass? I have 10 days to get a free retest. Below is a scan of the results. EGR was turned off in the tune, should it be turned back on?

Oh yeah, I actually drove it on the freeway between 75-85mph and right to the smog place. They put it right on. The tech even revved it before taking the actual test.

just re-enabling EGR should bring your NO down as that is what it is designed to do. should leave it enabled, doubt your getting much if any performance gain, and likely doing your engine harm.
