I had a test and the vacuum hose to the fuel pressure was cracked and during a retest, I knocked it off further and the HC was only 400. How HOT was your engine? I also, during other failed tests, had valves not fully closing that caused a high HC, but only around 400. Try setting your valves to .000 clearance. Check your O2 sensor also. I was able to pass with modified: cam, heads, power chipped ECU, ratio rockers, muffler, intake filter, etc., so it CAN be done... Robert
