Had some fun with the side-by-sides this weekend and hit some trails out here in Arkansas. Of course, you get two tuners together with tuned machines, of course we ended the weekend with a race.
My machine (camera car) is a 2021 RZR XP turbo with silicone charge tubes, BC intercooler (air:water to replace the stock unit that is known to crack), Dalton clutching, and a tune on E50. His machine is a 2019 Yamaha YXZ with a Weller turbo kit, MoTec ECU, and tuned on E85. I don't know what mine makes exactly, but his did 180whp on the dyno.
These things are a blast!
