The only thing you gained/lost, IMHO is weight. The velocity stack is the key. It provides better air flow at higher rpm's (and hence higher air speeds).
Stick in a JamesNow/Powernow and you should be all set.
MXA/DirtRider did a test of all these goodies for a YZ426. The article stated a loss of bottom end but an increase in top end.

As a caveat, the carbon fibre is known to let dirt through, and jetting changes are more of a b*tch. You have to remove the subframe to get the carb off. NOTE: I do have the velocity stack, so you may not have an issue w/ carb access like I do.
Also, you MUST remove your OEM frame mounted hot start bypass. The box size requires that teeny, tiny bit of extra room. You have to find another place for it.
