i have a hks fcon tuned for a hybrid turbo on my rebuilt motor. i can get my car to start but it runs for only about 30 secs and thats at 3k, if i let go of the gas it dies if i give it gas it will stay alive alittle longer. there is no cats or smog junk, i have an afc i was thinking about leaning it out a little or just taking off the fcon till it runs, but i know the fcon gets nasty at higher rpms but it making i run so rich its dies? this car is driving me nuts if anyone could help i would be greatful.
