Oh, and fuel pressure with the vaccum line is 24psi idle at 850rpms and 32psi at full throttle.

Thanks

I would try -35 across the board. The sensor type is pressure and should be 06/06. The arrow should be pointing up like this /. Do you have any gauges? Why do you have the Dec. air set? You really don't need that unless you are having trouble with stalling after hard pulls.

Well, I changed the censor type to pressure and no more cell for now. Just reving I can get 5psi and I had no cell. Once I put it on the road again I'll be able to tell you.

But I am still running too rich. I think my fuel is puddling because I have tons of black smoke coming from the exhaust. I turned the fuel pressure to 31psi just so I know I have the pressure but I am still getting to much gass.

Do you think all of the high volume lines, pump and fuel rail are making me get too much gass?

If so what can I do to lean it out?

still think your too rich because of afc settings.. -25% is pretty darn rich.

also, stock fuel pressure is 28psi idle and 38 WOT.

That -25 is at the top of the rpm band. I am talking about running rich when not under boost.

Maybe thats my problem. I have 8AN going in, but factory 1/4" going back to the tank. Would that make me run too rich?

Also, could my injectors be clogged and out of whack?

Another update: Still throwing cells at 8psi. I installed the AFC2 just as Apexi recomends.

Question, When you are doing the AFC Hack; do you install the AFC differently from what Apexi calls for?

no, but it's important that you have the pressure sensor in and pressure sensor out correct (white and yellow)

make sure in the sensor type list everything is 0 in 0 out. except for pressure which should be 6in 6 out.
