How about changing the fuel filter?

Yes I did that and a new fuel pump to

OK, then I suggest you check the fuel pressure, it could be the regulator dumping too much pressure, and if that checks good then on to the coil output, if it isn't strong then it could cause a power loss harder acceleration, if that checks then test the exhaust system pressures, even though it may not be plugged very much, and increased flow as during acceleration might be too much to handle all at once. That's about all I can think of at this point. HTH
