The car is an s14 with a s13 redtop in it. Mods:FMICGreddy BOV3" DP and straight through exhaustE-01 boost controller Walbarro 255 and 300zx Fuel filter8 PSI Boost
At idle the car is at 17:1 to 19:1 and under load it is anywere from 15:1 up to 18:1 The fuel pressure is 47 psi and plenty of volume no restrictions in the lines. The car has a miss and I am not sure if that is causing it to go lean or if the miss is a lean missfire.
