Posted in fuel and got no response so I figured i would try here.I installed a walbro 255-intank and now my car will not go above 4k when I floor it.If I slowly press the gas it will climb all the way to limiter.Before I put the pump in I had the car tuned for a hundred shot and my tuner was telling the pump to push as much as possible so I didn't lean out.Is it possible that the new pump is dumping to much fuel at wot because of this previous tune and causing my problem or is it something else like o2's?

Hook up a fuel pressure gauge and see if the pressure drops off anywhere.

The rubber hose might be swelling or coming loose when under full throttle, allowing fuel to blow out of the line back into the pump module.
