Well my problem is that I can't seem to accelerate my car without "pumping" the throttle. If I just go from closed throttle to wide open I can't seem to get the car to accelerate, even at idle.

Its an S13 SR redtop
370CC injectors

I replaced my MAF and am able to rev all the way to redline with ease.
I also checked my TPS, and its set at .37V closed.
I replaced the injectors with new ones from DW because there was always a cyclinder that kept flooding, even after changing the o-rings.
I've checked my timing at least 4 times already.
My vacuum is at 15Hg

I checked for boost leaks already with a boost leak tester and fixed the leaks. I dunno what else to look for really, so any suggestions would help.
