Well I sprayed the zex ls1 fogger at the track with the 175 jets in and I was pig rich @ 10.2 to 10.02 afrrrr all the way down the track.
Zex has a 28 in my fuel @ 58 psi. I am running c16 in the stand alone. Should I put a 21 fuel jet in inplace of the 28 or is that too big of a jump? I am trying to go from 10.2 afr to something low to mid 12s on the wideband.
Did you try reading a plug? we are having the same prob and think it might just be a faulty WB reading or running out of pump(no Standalone). It starts off good in each gear and works its way to pig rich. Going to try reading the plugs next time out.
