Runing Lean
 

I have a 93 del sol si, I have a votec fmu 12:1, Paxton adjustable fuel pressure reg, and a 14b turbo I run lean at like 9 psi, and my gas mileage has hit the fan, i am getting like 32 miles to like 5 dollars worth of gas is the crap normal

sometin' definatly wrong
get a S-AFC

Re:Runing Lean
 

doesnt an fmu and fuel pressure regulator do prettymuch the same thing??

sounds like that might be your prob,
either that or you have something installed incorrectly.

Re:Runing Lean
 

quite common, your probably maxing out your stock injectors.

do u have a inline pump? if you dont then thats the problem. at 9si times 12 your at 108 psi. plus idle fp. no stock fuel pump can support that.

thats my guess.
a tad more info on your setup and im sure we can tell u why

Well, first off, 32 miles for 5 sounds like you're running rich. Lean would be where you get 3200 miles on $5.

hahaha, I really dont know wtf i'm talking about
