Surging at Idle, running too rich?
I just finished up my turbo install, and I'm running a C&L MAF, I've clocked it a couple times, no solution. Timing is set at 10* with spout out. Not sure what total timing is.
I'm running a Holley AFPR, 42#'s, and the C&L Cal'd for 42's. Drove the car last night, had tiny spots where it would start to run good, then a minute later it would surge terrible and start to load up and miss. Any throttle (at all) while under load will lay a smoke trail even when out of boost.
At 1/4 throttle the car will start to build a little bit of boost then begin to cut and sputter badly. After it got to op-temp I shut the car off and it flooded when I tried to start it again. It tried to fire, but I had to hold WOT in order for it to fire at all, then it'd immediately die if I got off of the throttle.
I turned the Fuel pressure down to 30 psi and the car started and ran enough to limp home...
