This calibration service is intended for customers who want more performance from a properly running engine while retaining the existing PCM.\u003c\/p\u003e\n\u003cp\u003eThe Whipple Stage 1 calibration increases maximum power by more than 25 HP and 30 lb-ft of torque when used on the proper application with the correct fuel and setup. It also increases low-RPM power to help reduce plane time, while improving acceleration and throttle response across low, mid, and high speed operating ranges.\u003c\/p\u003e\n\u003cp\u003eThe factory RPM limit is raised from 5400 RPM to 6000 RPM, giving customers additional propping range and the ability to better use the available horsepower with the correct propeller setup. The calibration is designed for 91 octane fuel using the (RON+MON)\/2 rating method and maintains stock idle, starting, and drivability characteristics.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cu\u003eCalibration Features\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eStage 1 PCM calibration upgrade for compatible Mercury Racing 525 HP EFI applications\u003c\/li\u003e\n  \u003cli\u003eListed gain of more than 25 HP\u003c\/li\u003e\n  \u003cli\u003eListed gain of more than 30 lb-ft of torque\u003c\/li\u003e\n  \u003cli\u003ePotential MPH gains of 1-3 MPH with proper setup and propping\u003c\/li\u003e\n  \u003cli\u003eIncreased low-speed torque to help reduce plane time\u003c\/li\u003e\n  \u003cli\u003eImproved low, mid, and high speed torque for better acceleration and throttle response\u003c\/li\u003e\n  \u003cli\u003eIncreased spark at low and mid speeds for improved engine efficiency\u003c\/li\u003e\n  \u003cli\u003e6000 RPM limit compared to stock 5400 RPM limit\u003c\/li\u003e\n  \u003cli\u003eDesigned for 91 octane fuel using the (RON+MON)\/2 rating method\u003c\/li\u003e\n  \u003cli\u003eMaintains stock idle, starting, and drivability\u003c\/li\u003e\n  \u003cli\u003eFully compatible with SmartCraft-equipped vessels\u003c\/li\u003e\n  \u003cli\u003eCustom calibrations may be available upon request\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cu\u003eCalibration Service Process\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe PCM must be removed and sent to Whipple Superchargers for calibration service.
