Definitely a BD kit, should have the aux injectors in the bottom of the intercooler. If it's an out of the box BD kit, it should be a Garrett 2860 charger. There should be a tag on the cartridge or compressor housing with part and model numbers. There is lots of good information in the Arctic Cat Turbo section, back in the 2010 range.
If you send me your email address I can send you some of my boondocker numbers I ran on my 11 with that same setup. I also have a document that spells out what all the numbers and letters in the box mean. Most of the information I gathered from posts on here and calling Boondocker. If you learn how the box works and what each adjustment does, they are real easy to tune.
As far as riding at high elevations vs low elevations I ran the same tune at 7000 to 10000 as I ran at 1000ft but I would lower the CR number.
