ok i cant figure this out i have a JDM swaped auto(turbo trans) TT z32 @ 13lbs and when im at WOT easing into or just flooring the pedal the car bucks and rpms drop, it does when boost is at 13lbs but not right away just when the rpms are high, other than that it drives fine, no weird noises, no codes, no leaks boost holds, same power it just cuts itself off, before i had this problem my ECU was governed to 120 i could never go past that, but this is completely different, so any thoughts please!

 

Could be a sensor issue (TPS or MAS) or a failing fuel pump.
