I have a missfire at around 5600rpm under full throttle. my mods..

1990 integra gs
ebay turbo kit
10 psi
450 dsm injectors
255 pump
vafc (i know, unsafe, i dont care)

the car was running fine and now its not. i dont think i changed anything to make it do this. i have an ls. vafc was just what was availible. my settings are -22 from 1000-7500rpm. I dont wanna change them too much because my wideband sensor took a shit. I have another one on order but it will be awhile. I just thought that some of you may be able to help.

i replaced
spark plug wires
cap
rotor
plugs (gapped to .028)

any help on some tricks playing with the vafc will help as i am new to it. i know its unsafe, my motor has 210k on it, and i just dont really care what happens. but i would like to get the most from it before it does blow. sorry the thread is so undetailed, my other one didnt post.

CI BOOST FIEND
mine was doing the exact thing
my head gasket was blown and my turbo was shot....
could also be your tune, what are you tuned on?

For OBD0, the afc does fine in non-vtec motors and it actually does the job well, especially for turbo. As for the problem, check for loose hoses and check your waste gate.
