dyno vs factory

[mes_423]

I have a couple of questions if anyone can answer them that would be great.
thanks
1) which would be better a factory jet kit or a dyno one?
2) which has more power the dyno kit or the factory?
3) which is more expensive?
4) where do I get a factory kit online?
5) which would be cheaper to install(no way Im doing this one at home)?

Factorypro.com I think.  I like factory Pro jet kits because they use normal jats and no drilling the slide holes
