thats pretty high actually

 

[erebusknight]

try to stay above 11:1 if you can unless your really pumping out the psi and fuel. what about your fuel pressure? got it regulated enough? you dont want any unwanted high pressures bleeding past the injectors. I hear the Walbro 255 will put a squeeze on your stock FPR. any other running issues, etc?

 

[prostreetdsmx1]

how much boost are you running?

i'm running 18 psi ..car does'nt feel any faster then the 14b i just took off :-/

**Update

i just installed a set of 550cc cause i though the 680cc were to big ..it seems alittle better now its -30 the settings on the s-afc before with the 680cc i had to go -45 and it was still to rich ..i am running a/f at wot between 11.5 11.9

wow thats rish im running a 1st gen with a walbro 255 and pte 680s and it doesnt seem to be real rich. ill ask my tech when i go in to have my motor swaped. There is however the most iratating bubble in my fuel line right befor the rail, any ideas on how to fix, no leaks just noise.

You most likely have a boost leak.

Also I wouldn't go much leaner then 11.5.
