Bought sled new last year at the end of the season. 2015 viper mtx 190 Yamaha acc turbo kit installed by dealer. Not a lot of snow to play with last year so now that I'm riding this is what ive noticed. Boost seems to be high at 2000' 7psi was more I dropped it.**And lowers as I go up in altitude 5psi at 6000'.* Also it seems to run crappy after it is warmed up and sits for a bit. After I run it for a bit it clears up maybe 1/2 km down the raod. Temps outside were cold probably -10. I have looked and all plumbing seems to be ok.
