intermittent fuel cut/misfire bucking?
 
So after a lil cruise to Fredricksburg and back from NoVA (about 45 - 50 min each) most of which was on I-95 my FD was running great after a recent oil change and fresh plugs (stock nkgs). Boost was perfect the whole time. I was getting off the highway and i punched it to get past someone merging onto it and all the sudden I start bucking like hell until i get off the gas (this is coming out of 2nd). I'm baffled, my plugs are in order, i didn't spike, had 3/4 a tank, and it ran fine the time i was playing on the highway. WTF?!?

Bad gas?

I'd stay out of the heavy boost until you at least pass that one tankful, just to be safe..

did you happen to see at what RPM range this "bucking" happened at?

around 4500-6000 RPMs what are your thoughts, should i run colder plugs with my current mods(see sig)?
