WHIPPLE 525EFI STG 1 UPGRADE

The Whipple Stage 1 system is a computer recalibration that increases the maximum power by more than 25HP* and 30 pounds of torque*. Whipple also increases the low rpm power range for a decrease in plane time and a noticeable gain in acceleration. The factory rpm limiter is also increased, giving customers the ability to increase top speed MPH with proper propping. The stock RPM limit of 5400 is modified to 6000rpm where peak power ends.

Key features:

Hi-performance PCM calibration with MPH gains of 1-3mph.

Increased horsepower for increased top speed MPH.

Increased low-speed torque for decreased plane time Increased low, mid and high-speed torque for better acceleration and throttle response.

Increased spark at low and mid speeds for increased engine efficiency.

6000 RPM limit vs. stock 5400 RPM limit giving increased propping range and increased horsepower.

91 octane safe (RON+MON)/2.

Stock idle, starting and driveability is maintained.
