SR rough idle, bogging after revving.

[DJ_Sunrise]

hey guys i have an S14 blacktop with a greddy type-s atmospheric BOV. when i hit the gas regardless of how hard, the revs i take it to, etc, i nearly stall. ive seen my engine go as low as some 100 or so rpms. the tach will shoot up, fall fall faaaaalll all the way down to 100-500rpm, bounce around, and then even out at the 850 setting. Ive adjusted my BOV to the pt. of fluttering and i still have the same problem. i have a blitz lm fmic, and apexi power fc if that helps any. the other issue im facing is i've never hit more than 6psi of boost.. wats up with that?

check for boost leaks and ecu codes first.

did this just start happening and is it all the time?

did your setup change at all?

if your worried about it recirculate your bov. or tune with your power fc to lean your car out during shifts.
