Yeah, Impellitteri is freakin' fast as hell. Guitar One ranked as the fastest shredder. I find him annoying as a shred guitarist.

That's definitely him. Impellitteri is one of the fastest guys out there, though his alt picking sounds a bit sloppy at times (I can never tell whether it's him or his tone).

I can do that too..

He's just tremolo picking each note

Wrong. He's not trem picking anything.
Chris Impellitteri pretty much sticks to small alt picking boxes and moves his fingers the least of anyone I've ever seen. It makes him look like he's trem picking since it's hard to follow his fingers to different frets unless you look closely. Google Video quality doesn't help, either.
