Get the Dynojet kit. Its kinduv pricey ($50+), but it comes with DJs needle which has a lot smoother taper to it than the stock one. I bought the Moose branded Dynojet kit and it recommends 160 main and stock pilot for a modded airbox and stock exaust. For an aftermarket pipe, modded airbox, and high flow filter it reccomends a 170 main with stock pilot. Youll want to adjust your idle screw out too. I think mine ended up being out about 2 1/4 turns or so.

I second the dynojet kit. I have it in my '03 and went with the stage 2 (both stages included in kit) and it is great. Way more power and easier to start.
