Default Failed Emissions

Ok so I failed emissions my readings are: pollutant level, reading: 88.3 Capacity standard is 40.0
so how do I fix this???

Mods are: 4000 GSK, 215 injectors, new stock lift pump, adjustable over flow valve, timing done by me at 16.5...? I think, did it myself.
Did test 3 times and said they had to put the tool by the fan cause it got to hot. Got 6 days left to get it right. HELP!!!

You have to smog a 95 in Az.? That is stupid, even in Komiefornia they are exempt. To pass you ar going to need to turn the fuel back as far as possible and ease into it gently so it dont smoke. With the turbo lag when it is tested with a snap test most will fail anyway.

Was it fully warmed up? I have way, way more done than that and mine passes with flying colors. I was a little surprised it did so well last time, and the emissions guy said as long as you don't test a diesel cold it will pass every time, cold it will fail every time. Maybe my state has looser standards, but I was under the impression that was a federal thing. Regardless, another thing you can do is cut the wire for your convertor lockup so it will be impossible to really load it on the rollers.

I have never heard of this snap test that you describe.
