OK I have two sleds a awesome 2008 xp SHR 860 154 and for a back up 2010 xp x 146, and I'm looking at making a change next year. Do I trade my 2010 146 for a 2008 Nytro Ulmer turbo? Or do I send my 2008 back to Big John and have him extend it to a 163 and add more mods? Also I have never been around a turbo so I know nothing about them, but I'm 250 lbs and I want to climb higher. So I'm debating on what my next step will be.
