replace fuel filter first, if this don't work try cleaning fuel injectors. If this don't work you might have to consider a higher flow pump and/or injectors.

another thing I would think you might want to look into is an electrical issue. I know the AC is belt driven but it has electrical components as does the fans and fuel system. When you are under hard acceleration then you are drawing more on your electrical system and your car may be unable to support it. Definatly start with easy stuff first but if you could get a multimeter you should be able to get a voltage reading going into your fuel pump as you raise your RPMs. if that voltage gradually goes down then your fuel pump will sitll work however is would push less fuel. I dunno, just trying to come at it from a different angle for you.

If your fuel trims go negative , look at your catalytic converters to be plugging, The side that trims- is the side to look at.
If they go pos., look to fuel presure/ volume. A Good long fuel pres gauge taped to the windshield will show any pressure loss under accel. The fuel filter mentioned earlier is buy far the cheapest and most likely cause. Start there.
