Polaris limits the throttle opening of the 2017 Ranger 1000 programming to less than 30%. EVP reprogram the ECU to allow 100% throttle, revised timing, raised rev limits, raised speed limits, etc. Huge horsepower gains have been realized through these modifications to the OEM programming. EVP also build additional safety into their tune by lowering the fan on temperature by 20 deg F. The OEM fan on temperature is is too high (well over 200 deg F).

Evolution Powersports has vast knowledge of the Polaris Bosch ECU from their work in the automotive world. EVP have brought this expertise to the SXS market to extract the most performance from the Ranger 1000 engines as possible. 

NOTE: The 2017 Ranger 1000 is clutched for a 6500 rpm shift. This is FAR too low to get maximum performance from this engine. The Prostar twin makes best power at 7900-8000 rpms - therefore clutching is HIGHLY recommended.
