Improperly gapped plugs dont cause these conditions, it is either the fuel cut, which would happen for the technical reasons that Scott brought foward, there are simply limits in the stock ECU to prevent overboost on a full factory car, after you change something you need to remove these limits. Xede is a crappy bandaid for tuning if you ask me, stock ECU reflashing is ten times as effective. Piggyback systems in gerneral are a waste when you can alter AFR's and timing curves with the factory equipment. If its the snorkel, you will hit peak boost and when the condition occurs you will drop to 10-14 psi and fell like the car is going no where. Overgapped plugs will give you more of a stuttering feeling, not a solid stop. If the plugs are too wide the boost will blow out the spark. I think .24 is the recommended gap.

...i said to check only if he just replaced them...if not then that is not the problem
.027 to .024 is what i heard
get flashed and make sure they raise the fuel cut limit. i put on tbe and i had fuel cut so i had it flashed and rais fuel cut to 25psi just in case something happens. dont remove it!
Laf @ spark plugs. Good one, Bartek.
Hey, McDougal, it sounds like fuel cut as TTP mentioned and explained, but to be sure, did you hit a brick wall and totally lose power, or did your boost suddenly drop from full to 10psi or less but with the car continuing to accelerate (slowly)?

I searched for a link on how to remove the xede, but I didn't find one. Going backwards from the installation instructions it seems to be pretty straight forward, but if anyone could provide a link on the removal that would be great.
