I just got a 5-knob afc, and its setup ok right now. After 3000, the motor just pulls, a nice improvement over before. But from a stop, trying to get going, the motor just bogs like mad. The guy i had helping me tune the car, was saying that since i have a 255lph pump, that when starting out, my stock fpr is just letting to much gas in before the air can get there, causing my motor to bog, then die if i keep on the gas. Is there anything i could do to help this, the car ran fine before i wired the afc up, and now i'm also getting a CEL, but it goes away when your off the gas, and at idle sometimes, its not a full time CEL. Some help please, thanks.
 
Basically, a new question. If i just wired the 5-knob in, and left all the knobs at zero, shouldn't it run the same as before?? I Have all the knobs turned negative, the first one -2(if i go one lower, i get bad idle surge, and higher idle, one lower and the car barely runs, and bogs horribly when i give it any gas). And the second knob is very negative...very. The car runs fine once above 3000rpm though. Any help on this, the car runs, just not well at all now.
