I rode 1-800Oregon's turbo nytro with the MPI kit in it last year, and it was awesome compared to my NA Nytro, so I had to get the kit this year. He helped me install mine a month or so ago (well, he installed it, I tried not to be totally useless), and I too am really looking forward to testing it out.
I have been talking with Dustin at Outlaw Motorsports (where I got my sled, their help with all of my questions has been invaluable.) about the ECU update from MPI to run up to 200hp with the kit, and I will probably upgrade to that eventually - but I want to run with it without the update for a while before I drop the money on the ECU update.
I did cut some holes in the foam for the intake to allow for some more air to get through, same as 1-800Oregon did, and got another pre-filter for it just in case. Now that the snorkel kit is installed all I need is snow.
