empty boost??

[4BangerV8Killer]

iv been having some problems with my car...well what happens is sometime when i gas it my car will build boost and everything but it builds it very fast and i fell no power response...i tried swapping the turbo and MAFs twice. could it be one of my injectors not spitting fuel out? or a boost leak?

check for boost leaks, especially in the lower pipe and right where the BOV tube comes in (under the intake tube). i have a 2g and my problem was a boost leak. i think there is boost leak checker info on vfaq.com
