Default Car Pop's at WOT??

I have a 2000 T/A, i have an LS6 engine out of a 01 vette the car has been running for about 3 weeks now, i sent my PCM to TSP to get it tuned and everything was fine until last night. i raced a couple of friends and my car started to ack funny when i get on it around 4500 to 5000 rpm's the car will pop several times and does not pull hard but once it gets past that around 5500 and higher it starts to pull again it does it everytime i get on it. what could couse this any ideas on where i should start looking??

I already checked the wires last night and none are arking. i always put 93 octane fuel from the same gas station on the Air Force Base. I did put a can of Sea foam about two fuel tanks ago.

mine does it now...but I originally had fuel pump problems...I would start there...run a pressure test on your fuel rail...and see if you can do it at WOT...Ill let you know when I get mine fixed from doing this...
