1990 LT5 emissions fail - ZR-1 Net Registry Forums

Welcome onto the boards there...

Hows the burn temperature? Hotter burn means higher NO's, so you want it to burn a little cooler. This will also boost HC's however; what was the HC count? WAY under limit???

You're only 10% over limit on NO's; if you can bring down the burn temp a little, you should be ok on it...
