Hey guys, failed emissions today. I have an 89 GT, novi 1000, 30lb. injectors, 255lph high pressure pump, mac hi flow catted h pipe, dynomax 2 1/2 cat back, I am running fmu calibrated for the 30s, pro m meter also calibrated for 30s and supercharged. The smog pump equipment was removed before I bought it, so I am not running a smog pump. I lowered the fuel pressure to 36psi with the vacuum disconnected, but when I connect the vacuum line, it still reads 35psi?
My HC were 7.02 the limit is .8
My CO was 20.1868 limit is 15
My NOx was 3.4532 limit is 2.0
Should I lower my fuel pressure some more to get it down?
