Hey guys so I have been doing a fair bit of research on turbo kits for the xm's and rather than bying a new sled because I only have 1500 km on my 13 I figure i will throw a little boost to her. The majority of my riding is steep and deep it the tight trees but come spring I like to hill climb. I find this sled awesome in the early season but lacking in the spring. Which kit would best suite my riding, I want reliability with a few extra HP. The kits i'm most interested in are the TSS and the areocharger. Which do you guys perfer. Thanks Kyle
