1300' sled is still not pulled apart to see what's wrong. I just want to ride. Bought the last sled in the showroom today at skidoo. 800 backcountry.
I'm goin out for a rip. L8er

sorry to hear that. I've got 400 miles on my trail turbo so far and it absolutely rips. Hard to tell what was wrong if you didn't have an AFR gauge. Mine was crazy rich with the stock settings. I backed them off slightly for now. Waiting till the end of break in to dial it in completely but even with it running 10.5s to 11.8s depending on throttle position it is still fast as hell. It's just a little thirsty right now. I got around 10.5 GPM today in 97 miles of windy terrain.
