recirculate your bov if you are running an aftermarket one. do you have any boost leaks? aftermarket fuel pump? if you do have an aftermarket fuel pump, do you have an adjustable fuel pressure regulator?

you need a adjustable fuel pressure regulator. nismo type A. the 255 is throwing alot of fuel and the stock FPR cant keep up.
