For those that may not know, Silber has been around the snowmobile tuning industry for a long time. They build one of the best, budget friendly, turbo kits on the market. They are not new to this game, especially Polaris.
I talked with Justin Silber yesterday. He claims the tune is exact same as Bikeman's. Its 90hp, fully open throttle, higher rev, seatbelt safety elim, etc. The big price difference between him and Bikeman is you don't get the Bullydog tuner with it. Obviously a pricey unit. Turn around time about a week.
I just boxed up 2x ECU's and are sending them his way today. For $225 you can't beat it.
I wont have a chance to use them until Memorial weekend. I'll report back then.
