Ka-t, Gas pedel stalls engine, Idles great! :/

Alright, id been holding off on makeing this thread but eh, ill just throw it up and see if anyone can help me out
So Heres what i got going on:
95 S14 block and head
S14 upper manifold
S13 lower
S13 cams
BC springs/valves/retainers
head job /porting
new rings, bearings, gaskets, timing kit, ect
T25
370's
Rom tuned ecu
n62
S14 godspeed FMIC kit
HKS bov
3 inch all the way back, no cat
GP sports catback
ect ect

So my issue is this: I fire it up, it idles like a champ, smooth as butter..
But if i touch the gas pedal, it falls on its face and dies.. Like i cant let the clutch out because i cant add enough gas to compensate..
What i can do it gently press the pedal and it will slowly rev, pretty much keeping it right on the verge of dieing, i can get it to rev to like 3 or 4 k, it will actually build a little boost and blow off in this time.
But if i pass about 5% gas pedal it boggs and dies.. like you stop hearing combustion. if you remain past the 5% mark long enough, it will stall, if you releese it it picks back up and idles..

But so pretty much i cant touch the pedal or it dies, so i cant move it really ect.

Where im at:
When i had a emanage it showed me % of sensors and at that time the maf and TPS read great. but i havent checked them since switching to the new ecu but the emanage was sketchy so idk

I had a issue with leaky injectors, could it be flooding when i rev it and stopping combustion? Its my most likely option right now because i know it leaks form the bottom seal on all of them i think.

I checked the timing and its spot on

No Check engine light, code 55

Plugs are kinda old and crappy and may be fouled

It did this before i had the turbo hooked up awhile ago, changing spark plugs fixed it. i had a used set. but this time its not fixing it. but im thinking the injector leak is worse now and its putting the spark out there's a little smoke coming out the back... and it was way way worse before i hooked up the turbo.. im assuming the extra air is helping use up some of that fuel...

It ran great before, reved all the way and such, so this is kind of suddon and nothings really changed hardware wise

Anyway i was just wondering if someone could confirm its probably afr ( fuel drowning out spark) or if anyone else had has this issue and has found another cause like a sensor or somehting..

God thats sad to watch.. this is me staying in that 5% reving it and letting the clutch out alittle at a time so i could move it, then trying to get it to rev and failing.. i need to recirc my bov, hella Paul Walker right now lolz props to the gf for filming
wow, i just noticed my $140 pair of sunglasses on my trunk.. thank god for this problem! lol
