2009 700 rmk mid range bog/hesitation

[sketch96]

Having problems with my 09 700 rmk. after break in i developed the dreaded mid range bog/hesitation. I thought this was all taken care of in the 08's with the computer reflash?!?! Has anyone else had problems with the 09's??? Also been reading that the iridium plugs help this problem.....has anyone tried this and noticed anything?? I have already taped up the headlight knob and have not noticed anything in the airbox.

Thanks

If you are sure that it is not snow getting into the airbox?....... Then I would have the dealer setup the TPS sensor properly.... some of them are out slightly from factory.
