Engine stalling problems

[top_cat87]

Car in question is a Lancer CS3 with 4g93t conversion


I've had this problem ever since the 4AT gearbox was in there, in neutral or parking gear, when i rev >3k rpm after releasing throttle, rpm drops suddenly and too drastically low like 500rpm, sometimes the ecu recovers in time, most of the time engine stall

now the problem bugs me more since on manual now. rev rev, clutch in, rpm drop to low, engine stall. sometime after WOT, coming to a stop must brake and clutch in then engine also die cos rpm dips way too low

what could cause this? i arldy adjust idling to 800 from 680rpm previously but i noticed that the rpm still dips to the same level of 500 before stalling

what bov u r using?
recircultate,stock or atmo?

some atmo bov will stall 4g93t engine cause of releasing already metered air.
