Obviously the turbo is a little more noticable item on an slightlly underpowered sled. The skid would be more sutble change but you would still be able to tell the differences. The nytro had a trenching problem in 08 less so on the newer models due in part to a bad soft track but also due in part to the rear skid and approach angle. The TS or KMOD help the sled climb up on top of the snow better and have better more controlable weight transfer. So you would notice it being easier to get going again in deep snow. The sled would feel more stable climbing . I noticed that i was able to go to places that before i would just burry it big time without any issues. Hyfax wear was horrible with my stock skid and with the TS it is a no issue. On the 08 it was a night and day difference. On the later models it was less drastic because Yamaha was learning things from the aftermarket companies like KMOD and TS on what made a good skid for a mountain sled.
IMO it is worth the coin for sure. which one works better is debatable. Is it something you have to do right away that is debatable as well. will the sled work with the stock skid sure but it will work a whole lot better with it.
I dont have boost so for me The track made the biggiest change followed by the rear suspension, and then the front suspension. then the other mods where more about reducing weight which in turn effected the performance but in a more indirect manner.
