2011 600 E-Tec Summit Performance Help

[MMH2185]

Hi I ride a 2011 600 E-Tec Summit Everest 146" and I am looking for help getting more power out of it. The only thing I have done to it is put an AAEN can on it. I ride Michigan's Upper Peninsula and I need more power when hill climbing and the really deep snow. I plan on putting a full SPI exhaust on soon. I'm looking for advice on clutching mostly, possibly some kind of high flow air box/intake? Also would some kind of fuel controller make a difference? Any advise would be greatly appreciated!!!
Thanks

IMO, the best thing you can do is to get rid of those single ring pistons in favor of some GOOD dual ring pistons that were designed SPECIFICALLy for the 600HO...
