Default 240sx woes

my setup:
90 w/dohc ran perfect presetup
ssac bottommount mani
sr t25
sr 370cc
sr sidemount w/custom intake
aftermarket sr downpipe
sr oem blowoff valve (open atmos)
n60 maf

no other mods to the engine cept egr removal and gutted cat + catback
note: cat and catback are not connected bc its turned and cold outside.


fuel management:
bikirom 3.2.3
innovative lm-1 ( not hooked up yet)

it has sit for a while but gas has been removed and replaced with 91 and showed no change.

problems:
pig rich at idle
stubbles if revved at all
refuses to rev past 1500 rpms, ignores the gas pedal
can not check engine codes but has cel on
i can hear the bov psst vaguely at idle(i assume this isnt a big deal since its a tiny turbo)

my theories:
maf isnt wired correctly
when i unplugged the maf to test it the car did not change its idle

injectors are stuck/leaky
have not tested yet

bikirom sucks
ive changed between the oem ka dohc map as well as the "370cc/n60" map that was included in the setup with no changes. but does seem to upload/download maps according to progress bar.


any suggestions at all are more than welcome. this has been a headache for months.
