Just got home from Revy, we had to go very north but we found the powder. Rode 4 days, very cold. My Silber Turbo sled with the new external waste gate was not just fun to ride and push powder with, but it ran flawless. It comes on soft but its pulling hard from the start to the finish. It's as close to instant boost and responce as I could ever ask for, also you can play with the throttle in and out as fast as ya want and it was there every time. This is a very happy customer, big smiles after great rides. Now let it snow in Wa, so I don't have to get a Canada citizenship. Safe yr everyone
