I just put a new engine in my car and when I get on the gas, the car is fine until about 4000rpm range when the boost is really on hard. At this range the car really just looses a ton of power and feels like it is missing/sputtering and no power. I think the problem might be fuel related, but and sugestions would be great.

Mods:
stock [email protected]
huge front mount
costom front facing intake
q45tb
intake/downpipe
custom hardpipes
aeromotive a1000 pump/regulator to match and all the plumbing



there are more mods, but I thought these might be the problem esspecially that big fuel pump. What kind of pressure should I be running if i use a pump that size?

im not sure about the pressure i cant remember off the top of my head. you may however be on the right track with the fuel. generally the injectors are the first piece to be replaced. do you have a wideband or a fuel computer? the issue is probably that you are getting too much fuel to the engine without any way to control it. someone else can pipe in with the correct pressure.
