KA24DET won't idle ran fine before

[ZaK687]

Hey guys, so I've been working on my ka24det for quite some time and been working through the problems as they come. Ive been DD'ing my ka24det for at least a month now and one morning on the way home it wouldn't idle any more after i took an exit and came to a light. I can start it and give it gas and it'll drive fine but once i come to a stop the revs drop like a rock and the engine stalls. Ive checked my injectors, sparks, looked for vac leaks (going to go more in-depth on that), sprayed carb cleaner into the aicv and it didn't make a difference, done a compression test and I've recently cleaned my maf (less than a week). I am stumped, car ran PERFECTLY before, tune was spot on, only issue was minor valve stem seal leak.

My setup:
9:1 supertech pistons (150psi across the board)
370cc injectors
t25 hybrid turbo (twisted motion)
n62 maf (grounds combined)
255lph walbro pump

afr's 14.7~ at idle, 11~ in boost

let me know if more info is needed I need to get her ready for a competition in august.



EDIT: the day before this happened i changed the sparks out

EDIT 2: checked codes, only got knock sensor. code showed up before issue and tested a different sensor with no change so i ruled that out. Fuel pump is on a toggle and is producing pressure so thats also been ruled out
