Fuel cut problem need help
Well recently I had replaced my fuel pump, lines and filter. My fuel tank was disgusting. Crap everywhere. Well needless to say I had cleaned it out before putting my new items on my car.
Now the problem is that under WOT ill hit some sort of fuel cut. If I put the pedal to the metal the car bogs down. But while under normal driving conditions the car wouldn't do this. What could the possible problem be. I have some what narrowed it down to there probably still crap in the tank and it could be sucking it up through the pump and going into the motor. But I had consulted one of my co-workers friends and he had said it could be a number of different things. Nothing in too much detail. So it would be greatly appreciated for everyones input and I can remedy this problem, before something happens to the car.

How much boost are you pushing? Do you have the stock ECU?
If you are pushing too much boost ( over 12psi) on the stock ECU it will hit over-boost fuel cut.
If you are at stock boost levels then when does the bogging occur?
If it is around 3700 rpm then you have a problem with the secondary injectors not spraying.

Remember, there are 2 fuel filters - 1 a sock filter ahead of the pump in the tank, and the usual fuel filter above and to the rear of the diff.
