why is my car stalling

[IanS13]

Today after some time of sitting in my garage i drove my car to work, the car runs and drives as normal but it stalls at every stop light, i can keep it running by hitting the gas but if i don't it stalls, i have t3 turbo 370 injectors safc2 dyno tuned, walbro 255,blow trough maf setup, can any one point me in the right direction, also my car is hard to start if it sets for like a hour it's hard to start. i need help

What is your spark plug gap?Also maybe why it's hard ot stall.Maybe not enough spark created to burn the fuel comign at low rpms.So it makes your car stall.Yuo shut off your car and at lwo rpms it's pourign fuel so kinda foulign out your plugs.Most common issue of stallign when coming to a stop is BOV.yu atmospheric?

I would check for a blown coupler on your intercooler piping. I had problems with a elbow that came off of my turbo outlet to hot pipe that would blow off when reaching about 10psi. It would run alright just extremly rich and would stall at stops unless I was on the throttle.

all the couplers are fine my gap is 35 i run a blow trough setup so even if the bov was open it shoyld not cause a problem like i said it hold boost and runs fine it just stalls at stop lights.
