Z32 TT buck at WOT

[tt2x2tt]

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! thx

What are your plugs gapped at?? May need to adjust smaller (ie 0.035")

i know how bad plugs feel but it aint that trust me, But i took it for a drive again and now its normal again, i think its a bad sensor for some reason, plus when it was acting strange the transmission would shift up down up down only sometimes driving normal at about 20-30 mph, felt like the car was being jerked back n forth making its mind up to go into 2nd or stay in 1st

Clean/check the MAF (could be dirty or bad connection) and check/replace/adjust the TPS (variable resistor that may be worn).
