Hi fellas, I'm looking to pipe my 04 Summitx800, the only engine mod I have is a Can. the rest of the sled is stock. If I pipe this, is there any jetting required as it has a DPM. Looking for some advice, I've been sledding for a few years, but haven't really thought of modding the engine, but since most of my buddies are starting to get extra HP, I need to keep up. Any Hp Mods suggestions would be awesome...RIDE 'TIL IT HURTS!
