Doing some tuning for a customer’s RZR we just installed our Z1 kit in. Built engine with upgraded engine and turbo. Tuning at 34 lbs. boost on E85. It also has a flex fuel sensor so he can run anything from ethanol free fuel to E98. Got to love the Vipec tune we have setup for it. Of course, the tune has to be turned down for a lesser grade of fuel to keep for having detonation. So, we have 5 tunes setup for the different grades of fuel at the turn of a knob.

Here is the video
