just make sure if your gonna port your tb, you take your time the first time and do it right....ive seen people dremel straight throught the lip on it....ive done about 15...and i just take my time on each one...they turn out real well, and it is a good mod...will show better gains with manifold to...just remember with a UD pulley, youll need a puller, patience, strength, new belts, and a new bolt....for about a 7rwhp gain...i got about 8 from porting my TB....3 different grits and time

+1 for port. i didnt notice much if anything with the u/d pully may be from already having a ewp(i did notice that) but, the tb port was a noticible mod and didnt cost much, a few sanding rolls and liquid metal polish.
