Polaris Pro R Supercharger Additional Tune
Precio habitual$ 200.00
/
Every supercharger kit ships with one custom tune. This is the second one — for when you change fuel, change boost, or run different fuel in different places.
91 → 110 → E50 | Matched to your kit's boost level
- 380 / 425 kit: up to 8 PSI, tuned for 91 octane — clean, consistent pump-gas power
- 460 kit: up to 11 PSI, tuned for 110 octane — sharper timing, harder pull
- 500 kit: E50 — the most boost and timing the system runs
- Each tune is written for your kit and your fuel, not a generic file
Buy the tune for the fuel you'll actually be running. Running a 91 tune on 110 leaves power in the tank; running a 110 tune on 91 is how engines get hurt.
All orders are hand built once payment in full has been received. Typical ship times are 1-3 business days
