hesitation at WOT!!!!!!!

[koukitype_x12]

i just finished my swap and i have noticed that if i try to ive it full throttle t just misses and sputters around= no or slow acceleration. it responds ok at half throttle but when i try WOT it wont have it. i have already checked the mafs sensor and wires, checked for boost leaks, checked volts on TPS, replaced fuel filter, regapped spark plugs to 0.28 and checked ecu for codes. ANY SUGGESTIONS??????

-o yeah here are the reading for the tps sensor at closed throttle and WOT.

closed=.404
open=4.128

are these right. + if anyone has an extra tps sensor or alterna
tor.

thanks,
