question about rpms and redlining????

I got a 95 stang that has a 357 DSS block. the gears are 373's and the cam is a E303. Alright now let me explain what the problem is.... The car has some routy balls but when i get to about 4700rpm the car just hesitates and boggs BUT it shoots right up to 6000-6500 without the car movin faster... When i say boggs, the car just stops accelerating and losses power but the damn rpms just keep shooting up...
Could this have anything to do with the gears, or the cam, or is it just not getting enough fuel(195fuel pump), or???? I dont no i cant figure it out.. At first i thought i just needed a tune up so i got a full tune up. Then I thought the car needed to be tuned so i got it tuned. Neither helped out the problem..
Can somebody please help...

I understand what your saying but its doing it in the same rpm range everytime. Is it because its in a higher rpm range its slipping. I dont understand why it wouldnt slip when i take off in 2000 or 3000 rpms.

another question.... Im running 30lb injecters with an 80mm MAF and a 75mm throttle body... Could it be possible that im not getting enough fuel with a 190lph fuel pump?????

THANK YOU ALL FOR YOUR ADVISE AND KNOWLEDGE!!!!
