I'm a pretty mechanical person. I have definitely learned a lot about turbos since I jumped into Turbo sleds. I don't do most my wrenching because I don't have the time but I have had nothing but horrible luck with 2 different BoonDocker kits. I said I would never turbo again. Then the lovely Christopher had me all smoke and mirrored into the MPI kit. Had nothing but early season problems. I figured out what was up after MPI told me I needed to buy their new air box in which I told them I'd rather pull the kit off my sled and shoot it up with my .50 cal before I spend another dime on a kit that doesn't run. I bought the kit from a guy on this forum that thinks he is god's gift to snowmobiling. If you don't believe me just ask him and he will tell you. He wasn't any help either. I got it running good now. I honestly don't have a lot of faith in these guys when you talk to them about their kits. They never seem like much help. Money isn't an really an object for me. I prefer good service and a product that works as advertised. Turbos are for rich people who are expert level riders. I would talk anyone I can out of getting a turbo. 97% of people can't outside a stock sled so they really have no business getting a turbo except to show off they have lots of disposable income.
