I've finish my rebuilt with forged internal last month and cant drive the car because im just ****ing rich...

I dont want to scew my rebuilt because im running to rich so im looking for the best way to run the car safely.

Im running right now with 440CC at 22psi on sfmu. 6AN from fuel rail and a 3/8 fuel hose for return. Sometime I got cel for bank1 rich... my tailpipe is damn black but no black on white bumper. My plug are holly black... my narrowband a/f will read 14.4...14.8 at idle but if I just press the gas a little it will go to 11 than 10 than 11... at wot its 10 for sure and for long.

My car dont pull like it should be, I thing its because of too much fuel coming.

Since I dont want to run more than 15psi, the cheapest way would be to sell the 440cc and put some 370cc RC injectors (the one I can lower fuel pressure and keep a good spray patern) I think 370cc would a little more easy to tune ??? Else I can sell the sfmu and get a portfueler but damn 1000$ for 15psi?

Help me... I want to run that car soooooooon, oh and ive ordered my exhaust systeme cause now im on stock one.

So now they have narrowbands that read at idle and part throttle? Did you mean wideband?

You dont need a portfueler to run 15psi dude. I ran 18psi on the same injectors you have now which used to be mine, a sfmu and 255 fuel pump. you have something messed up or something.

stock exhaust is your first problem. lower your idle pressure down to 18-20psi.

and nbo2 dont read what your saying it does so you either you have a wb02 thats reading that or you do have a nbo2, which one?

When I said 22psi its on the sfmu fuel pressure not on the boost gauge ;p Ill never run 22psi of boost anyway :)

I dont have a wideband, my narrow is the apexi one that came with the turbo timer. If I read in voltage I see the 02 jump to .98...99 most of the time. All reading with that gauge is not accurate if not under wot ?

I cant use wideband, im waiting on my exhaust because I will get 2 bung.

As for the exhaust, ill jump from stock to 3" soon but I dont think this will stop the rich mixture.
