Ummm, not an apples to apples comparison if you're going to take the whole SLP kit to compare to the price of a turbo. By the time you include all the clutching, venting, and so on, $4000 is the least you're realistically going to spend on a turbo. No matter how you cut it, a turbo costs significantly more. With regard to hot vs. cold pipe power, it's pretty much a given that the twins aren't going to do much for you in on/off throttle riding – that's always been the case. So a guy who rides trees a lot is going to be disappointed, but turbos don't shine there either.
Just to recap what people are saying: 850 twin has more power on a long run, weights slight less than stock (that's probably all in the can), and I'll just add it should have no effect on longevity/durability. Downside is, in on/off throttle riding there's no benefit, and they're loud. Oh, and the tune isn't optimum, (although that means there's more on the table eventually). So, an even substitute for a turbo it isn't. And some riders won't see more HP in their typical riding. Those riders shouldn't buy it. But some riders do more long runs and will see 15+HP with less expense, complexity, and a significant weight advantage over a turbo. Doesn't have to put up the same power as a turbo or benefit in every condition to be a good product, guys. You can spend $2000 easily on a stage kit too, guess since it's not a turbo, that's not worth it either?
