my buddy just did his xp. It is a boostwurx kit from absolute power and performance out of canada.
He has only had it out twice. The second day the chaincase blew up. He called and asked the dealership about taking the secondary out. They never said anything about a collar. When we put it back together the collar wasn't on the shaft. that was are fault.
Not enough time on it. Seems like it is going to be awesome. Still needs some tuning. Have a few more questions to ask them. There customer service has been good. They told him to bring it up and they would tune it in for him. They act like they want it to run.
the kit is very clean. We did the install ourselves. Easy enough but time consuming. The xp is a pain. Everything is tight.The nice thing about doing it yourself is you know where everything is.
Boostwurx and turbo boyz are your only two choices that I know of for ski doo. I guess there is cpi but I would be leary of them after I bought a pipe from them and they couldn't tell me what rpm it was supposed to run.
Probably the only difference between boostwurx and turbo boyz is boostwurx has an intercooler.
I am pretty sure it is going to have the power of my mcx nytro but I am going to be crying if it runs awesome and is dependable. The lighter weight will make it way more fun as an all around sled. It is going to be hard to beat the dependability of the nytro plus I don't have egts and all those guages to look at.
