Hesitation Gen 1

Cant figure out why my Busa is hesitating between 4K and 5k rpm. Doesn't matter the gear or the speed. Once it clears 5k the bike takes off and before 4K it has all the power also. Mods are a yoshi full exhaust, power commander and restricter delete. I'm going to be doing the air box mod and ram air scoops this weekend. Anyone have an idea what the problem is?
 
Are you running in dealer mode to see error codes? I seem to recall that does something to the mapping and creates a hesitation.
 
maybe run a can of wynns power charge through the tank with about 2 gallons in it. If its a clogged fuel problem that might take care of it.
