I checked them all out. Did alot of research in regards to the benefits of this particular turbo manufacturer vs that particular turbo manufacturer. Contacted a few friends that have ALOT of turbo experience, they ride one and have ridden/owned most of the other brands. Then, I called the Turbo Dealers themselves and visited with them. I asked alot of questions in regards to their fuel controllers, possible issues with the kit itself, ease of installation, how the gauges mounted and where they mounted...etc. BUT, most importantly are they going to be there for me after I/my snowmobile leave their shop?
There was ONE Dealer of a Turbo Manufacturer that I didn't have to ask that question. The Dealer (Next Level Powersports) aka Boston Racing here on SnoWest...came out and specifically told me that he will support me and be there for me while I run his turbo. Hell, he even gave me his personal cell number (He does this for everyone) and said "Call anytime, I always answer if I have signal, even when I'm riding and I'm on top the mountain". His shop is about 1.5 hours away from my house, this was huge for me. Just in case I need huge help, new parts, etc. I can load the sled up and be there in no time. Seriously, I probably would have went through Next Level even if they weren't the closest dealer, I have that much confidence in them.
Needless to say, I went with SILBER Turbo. I seriously think all kits are pretty good right now, some have better this or better that. This will be my first turbo and customer support was big in my decision. Plus, the pricing is great too.
