Help! on fueling needed

[Endles]

Ok, ive got a B18C in a B16A delsol using hondata stage 4
I finaly got everything together in the car the other day, and started it up for the first time, and it runs very rich! I mean like its getting bout 3 or 4 times more fuel than it needs and promtly stalls itself.
Im running 550cc injectors and stock fuel pressure.
Ive modified the injector size in the comp.
Any help much needed.
