Turbo RZR Stages:




Evolution Powersports is on the bleeding edge once again with our lethal Polaris RZR XP Turbo ECU ReFlashes. These tunes will transform your already fast Turbo into an absolute animal! In addition to boost, fuel, timing, rev limit and speed limit changes, we also help the cooling system issues by lowering the fan on temperature by 20 Deg F. This makes a huge difference in the average temperature the engine operates at and prevents run away coolant temps on hot days and high loads. Each tune is customized with fueling corrections for intakes, exhausts, etc. We can also customize you tunes for fan on/off temperatures, pedal response, timing and more! Our two RZR XP Turbos have about 500 dyno pulls each to verify horsepower gains and have been rigorously tested in the deserts of Arizona in 115 Deg+ temperatures, Glamis, CA and Dumont, CA, and at high elevation in Steamboat Springs, CO. Evolution Powersports has 2 dynomometers – A Mustang SE500 and a custom UTV Dynojet 250ix with torque. Nobody tests like we do!

Evolution Powersports was the first in the industry to tune the RZR XP Turbo and haven't looked back since. Nobody else in the industry has our tuning experience. While others play catch up, we are continuing to refine our tunes for more power, drive-ability and safety. Evolution Powersports is THE innovator in UTV Performance.
