SAFCI's NE-point

[cavillac]

I am trying to just get my 2g to not misfire under stock boost with my 16G, the fuel system should be plenty to support 9psi (450's,Walbro 190, 48 psi base fuel pressure) on my 16g, I have tried everything to get it to stop missing under boost and now I'm curious if I'm missing something with my SAFC..

Can anyone explain to me what the NE-Point PID modifys? From the manual it says it is for the Air flow % correction point but I'm not sure if it is relevant to what I'm doing..

Any help is great, I've tried new plugs and even disconnecting the knock sensor and the O2 sensor is brand new, no boost leaks.

It's most likely a spark issue. Make sure you have normal NGK (BPR6ES, BPR7ES, BR6ES, or BR7ES) plugs gapped at no more than .028 and that your plug wires are in excellent condition and CLEAN. If there is a white spot on the plug wires, that's where the spark is grounding out. Also be sure that those stupid caps that thread onto the top of the sparkplugs are tight (they like to spin off). These cars are very fussy about plugs and wires, because of the turbo and that the plug wires run way down in the head.

thanks, I just put BPR6ES in today they were gapped smaller than .035" because my gapper didnt fit, I use 92 octane and it doesnt feel like fuel cut because the car still accelerates just with a miss.. It has autolite platinum wires on it (came with the car).. I think I'll get them warrantied out though..

Gap them at 28 or less. 35 is too wide.

.028 is what I run 30psi on. Yours are gapped way too wide. I would think about some new wires if that dont fix the issue. Go with NGK wires. Thats the only wire I would ever use again.
