i recently bought the Advantage Performance Pro ATV Power Pack and upon waiting for it to arrive i decided i might as well get an air box as well. so i got an airbox off ebay and now i'm wondering what other people have experienced with these addons?

i expect a noticable difference but i'd just like to see what other people have to say about it. the power pack kit was the most expensive at $148 but i bought it from global moto outlet so i've invested a little over $240 on this whole deal.

i'm also wondering how much its gonna cost me to get it re-jett'd. i am figuring i can install the air intake and air box myself maybe not the 'pro design billet base plate'? but probably not the jets.

post here your opinions i'm dying to hear!

Post your machine make and model if you want help.
Don't sell yerself short. I figured messing with carbs was too technical and that I couldn't re-jet as well, but I did it. Not a big deal really. Get some instructions of the net for your quad and take your time. Now I don't even bother with the "kits". Just pick up the individual jets I think I'll need, and experiment. Once you do it, you'll laugh at the thought of payin' to have it done.
