So, if you havn't read my previous post a few weeks back I have been having trouble with the vortech SFMU. I am running a custom turbo kit with th star turbo and manifold. Tial wastegate set to 8.7 pounds and a greddy Type RS BOV. Fuel system is a walbro 255 high pressure, accel 30 pound injectors, and the SFMU. I have been running the 2.72 disc for he past weeks since i have been turbo and even with the idle fuel pressure set at 40psi, during boost i would get about 50-55 psi and lean out. (boost is only running 6psi right now prolly cause of the front mount). So i decided to put in the largest disc with no ring yesterday. I set the idle fuel pressure to 40psi and made a few pulls. A perfect 11.5 on the wideband at 6 psi. I drove all day today with the largest disc and the only problems i have seen are when i hit bumps the fuel pressure will shake a bit. Also, when dropping into neutral the car will idle at about 1500 rpms while rolling, but the second i come to a stop it idles perfect. What the heck is going on lol?
