i have these installed. i have the dark spring, 2.72 disk and biggest ring. i have the static set to like 40-45, and the idle is around 25. now the idle seems to be low. i have the restrictor in there, and the sfmu has its on vacumm line off the manifold. im running the accel 30# injectors. running 7psi (hrcstg2) i have the s-afc installed, but not linked to the map sensor. i have blue wire connected to the o2 sensor. it reads around .94v-.92v WOT w/out boost. when boost starts it goes to like .91v then down to like .89v-.88v . i dont know why it leans out so much with my setup.

What are you using as a fuel cut defensor? A missing link, or the HRC wire up FCD?? I had my HRC FCD go bad, and was clamping the map voltage too low, causing the injector's to not spray enough fuel, even with lots more fuel pressure..So check that out and get the missing link if you can..

i have the missing link. i might get the corbin's gauge. give me a price whomever emailed me. also, where can i get the boost bleed valve? i got my kit used, so i dont have any parts extra.

I have the 30lb inj. also and I have the spring that came with the s-fmu. I but I have the second biggest ring in. I am also running about 25psi fuel at idle but I think that it is a little rich. I do not however run any fuel cut defenser. I disconnected the hrc fcd and have yet to get the missing link. Maybe the missing link is bad. I am not sure what exactly is causing your problem wish I could help more.
