460 crank horsepower on 110-octane race fuel, with the full exhaust system, on a stock Pro R engine.
Up to 11 PSI | 460 crank HP | 110 octane | Full exhaust included
Race fuel is what lets us lean on timing. Same engine, same driveline — the difference between this and the 425 is what's in the tank and what the tune does with it.
Run 110 and only 110 on this calibration. If you'll ever be pump-gas-only, buy the 425 and add the 110 tune later for $200.
All orders are hand built once payment in full has been received. Typical ship times are 1-3 business days
