car ran great then no 3/4 WOT

[86 got boost]

86 GN... I just replaced fuel pump w/ new walbro pump w/ hot wire and a new GM sender. RAn great..., then no 3/4 to WOT
Fuel pressure at the time it's happening is 60psi w/ no flutter of the needle or drop pressure, idles at 42psi ... car pulls hard but 3/4 throttle up to WO its like you took your foot out of it, shut the car off, and the waste is being let go at the time, If you let out the throttle and then back on...
pulls then bogs (unless at half throttle down is ok)....
Im running big stuff 3 also, no changes and all looks to be ok/ same since pump change?...
Any suggestions, give me some idea's...
