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
thanks
Tim

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.
