just finished up my turbo kit acouple of ?'s
 
Well here the deal. Pretty much put together a turbo kit. here some details then i'll follow up with the ?. I have a mitsu TD05 off a 95 eclipse, tial waste gate, RFL blow off XS boost controler, 5.85lb spring in the waste gate,2002 WRX fuel pump, BEGI rising rate regulator, FMIC, Piping is 2 inch to the FMIC and 2 1/4 to the Throttle. 3 inch down pipe still the old 2 1/4 back, I'm going to 2 1/2 inch, I'm pushing about 40 psi of fuel at idle, and i just above 75 at 6 psi of boost. now my ? is sometime it tends to studder at half throttle. Why? Some one told me cause of the risin rate of fuel it floods. Does this make sence? Another thing is my A/F gauge shows its running on the the leaner side as soon as it starts to build boost, I do have a voltage clamp. Should i get injectors i was told that wouldn't help. Its the ECU that F*#kin erey thin up. So what do you think :asshole:
thanks

Sounds like your base fuel pressure may need to be adjusted.
With the vacuum hose removed from the BEGI,(make sure you kink the hose so you won't have a vacuum leak) what is your fuel pressure at idle? It should be about 50 psi (plus or minus 5 psi). The pressure from experience should be anywhere from 45-55 psi.
If the engine stumbles or spits out black smoke, you probably need to pull back abit of fuel, and if it seems to have a flat or lean spot, you need to add abit of fuel.
