Turbo guys I need some help. My car runs great except it still runs rich. My Tomei rising rate fuel pressure regulator was set at approximately 40psi but my car WAS hitting 10:1 on my wideband. I decreased it all the way down to about 32psi still didn't rly help. My friend suggested I disconnect the vac/boost line off my FPR so its essentialy a non rising rate fpr. I tried it and lowered the PSI down to 32 psi and it runs a lot better but still dips in the 10s on my wideband. I don't wanna have to lower the fuel pressure less than 32psi it just doesn't seem right... any idea why it's doing that? What are your fuel setups and pressures?
