Whipple, the pioneers in PCM555 development and well over 10 years of R&D are the authority of PCM calibrations. With full PCM control, Whipple can offer customers many different options for stock and modified engines. Whether its the Whipple Stage 1 and 2 packages or custom calibrations for your application, Whipple can easily handle it with incredible accuracy and a ultra fast turn-around time.

STAGE 1
The Whipple Stage 1 system is a computer recalibration that increases the maximum rpm level while maintaining a conservative timing curve for 89-octane gas. This calibration is designed to be conservative and reliable like stock, but a higher maximum rpm level for more prop selection. Stage 1 achieves only modest power increases such as 8-10 foot-pounds of torque and 8-10 horsepower.
Key features:
• 5450 RPM limit (5250 on Base models)
• 89 octane safe

STAGE 2
The Whipple stage 2 maximizes the power output of the stock engine by running 91 octane or better, increasing the maximum spark advance, increased ignition power from the individual coils, denser air charge from the low temp thermostat and maximized air-fuel ratio in each individual cylinder. Calibration increases torque levels throughout the entire rpm curve while making more peak hp for increased speeds. Customers report far cleaner transoms (less soot) while increased throttle response.
Key features:
• Hi-performance PCM calibration
• Low-temp thermostat
• 5450 RPM limit
• 5% - 8% power increase over stock
• Increased acceleration with increased torque output

NOTE: PCM'S MUST BE SENT TO WHIPPLE SUPERCHARGERS FOR CALIBRATION SERVICE ALONG WITH RECEIPT, NEW PCM'S ARE AVAILABLE UPON REQUEST. TURN AROUND IS NORMALLY 1-3 DAYS.

CUSTOM CALIBRATIONS:

Whipple has full control of the PCM calibration, whether you just want to update from an earlier model cal to a new model year, work with your custom cam or engine combo, whether your tired of the factory transom soot issue or anything else needed, Whipple can support your needs. Use the custom calibration worksheet do list any changes from stock.
