Hard Core Tuning has become an industry leader in ECU programming through real world field testing, desert racing programs and global sales. The HCT signature ECU will transform your already impressive 2018 or 2019 Polaris RZR XP Turbo S 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 approximately 20 Deg F. This makes a huge difference in the temperature the engine runs at and prevents run away coolant temps on hot days and high loads. Each tune is customized with fueling corrections for your application. Minimum 91 octane fuel required for all performance tuning applications.
We have 3 ways we can get you tuned:
You can either bring in your ECU to our facility and we can flash it by appointment in about 2 hours or you can mail it to us and we can reflash it usually same day or next day and mail it back.

You can flash it your self using our HCT Flash Cable for an additional $225.00 This gives you the ability to change file and flash back to stock at any time with your laptop at home.
