Passed!!! just one question.

Put on the Cat from Reds to match the THDP, put in TT's Emission chip, backed fuel pressure from 42 to 38 and reconnected the charcoal cannister vacuum line and the GN passed! This was the first and only test I have ever had to do as the car was registered at a P.O. Box in the next county over, but lost the box. Just a quick question for those in the "Know".

What would cause the HydroCarbons to be so high during the high RPM test? This is not on a dyno, they just keep the car at high RPM in park. In under 30 minutes upon returning home, that cat was off, fuel pressure back up, and the street chip was back in

Just a quick thank you to Eric for his emissions chip, the car idled (& Smelled) great with it.

Sent answer to PM. And looking at the readings, that engine is running too lean.

[Roc87]

yeah, probably was too lean. Less than 10 miles on the cat, and the SS has already turned a funky color. Eric suggested 38# idle with line off, maybe that was too low at this altitude. Oh well, good to go for 2 more years
