Terrible problem with bogging down?

[Trizon]

Well to start, my AFC is untuned, and im waiting to get someone with proper logging tools to do so.. As far as that goes.. Just had everything rebuilt -- I was driving tonight, then all of a sudden terrible bogging down and misfiring @ 1500 - 2000 rpm... Check engine light came on.. was running fine earlier ? -- Any tips? 95 gst, afc, ebc, fmic, 550cc inj, 255lph pump, 18g turbo? -- Anyway, when is it running rich? negatives? or positives on the afc chart? Anyway, need to figure out why when i hit the throttle down, it bogs down severely and starts misfiring..

One thing i noticed this morning, was when i would attempt to rev it, the turbo would build boost, i could hear it inducting air.. in nuetral * -- guage sits at -10 with this issue, normally around -15, but as soon as i rev it i can hear it building up and see it at 5psi out of nowhere, black smoke out the tailpipe as well.. signifying its rich, but still? i cant figure out why it runs okay, then bogs down and acts up..

somehow the cable hookup to the MAS got disconnected ** wonder how that happened? -- back in and running fine!

I really can't see it running "fine" with 550cc injectors and a zeroed AFC.

Does it bogg down when you trying and boost even slightly? if it is fine off boost and boggs on boost then your car is pulling timing, I have the same problem. Are you on the stock sidemount? If that isnt your problem then it deffinatly has to do with too much fuel being added at to low a airflow/rpm level.
