Now this gets interesting!:shrug:
Hows the calibration on your maf?
When was your fuel filter last changed?
Maybe theres some sort of problem w/ the boost cooler kit.
Did you check for codes?

The MAF is calibrated for the 42lb injectors.... other than that, i dont know how it is calibrated....

fuel filter was changed about 3 weeks ago.... however the filter on the bottom of the fuel pump looks kinda dirty but it cant be that old.....

There might be a problem with the snow kit.... i dont know how to adjust the pressure on the pump, i know there is a pressure adjustment on the pump itself, but i dont know of a way to actually know what the pressure is... i could be pumping too much in therefore "quenching" my spark...but if that were the case, how could my AF ratio be 12.5 still i would think it would be much more rich

i didnt check for codes but i dont have a Check engine light either :shrug:

i have looked under the hood after i turned the car off and system holds fuel pressure after the car is off.... hold long does it hold? im not sure, i will look into that

how do you check for a bad regulator? it seems to work... i can change the fuel pressure with it :shrug:



on the 2 tubes coming out of the fuel tank above the fuel pump.... one is fuel out, what is the other one? extra fuel back in?

Just cause there's no check engine light dosent mean there arent any codes.
You can buy a code scanner for like $20. Id also go to Snow's website and do a little research and maybe talk to one of their tech's.
You could have a bad connection where your chip slips into your computer in the kick panel. I dont know just throwing out a few ideas.:shrug:

welp, i bought a new regulator today.... this one is for sure 1:1

got a new cap and rotor for my distributor...

talked to david at snow today and he told me how to check what pump i have and what nozzle i should have and how many turns on my pump to get the right pressure for my nozzle :nice:

so hopefully when i get all this stuff on and go back to the dyno i will have fixed the problem
