First my sled is trenching really bad on hill climbs. What do you do to remedy that? And second, It just don't really feel like all the horse power is making it to the track. I've weighted the primary witch got rid of a tun of slipping and heat, but it still don't act like its reaching its potential. So my question is; what things can I do to the secondary to maybe help this out. Oh yeah I have a new xp 154. I was getting high marked by an old artic cat mountain cat 900 by like nearly double as high.
