I've rode my buddies Nytro with a turbo and I must admit, stock I'd never buy that sled, but with the turbo it is fun. Heavy, but fun.
With the kit he has you have to think a bit ahead of what you're doing to allow the power to come in before actually needing it. There was a decent amount of lag if you don't keep it spooled up, but when it came in it's a pretty good rush of excitement and adrenaline. Totally transforms the underpowered and heavy Nytro into something that's got some spunk and enjoyment. Just don't get it stuck.
As for those questioning my boss's 1000, I'll run it by him next week. I think it's still stored here at work so I could get pictures too. It's been stored in a heated shop with cover. Like I said, I'm pretty sure he said it had 600 km's, but when I got it running for him last time it had something rediculous like 200K.
