Ultrashift P5.4 PRO R Tuning Chart Overview

 

This chart provides guidelines for vehicles running 32” tires at sea level. Adjustments may be required for different terrains or conditions.

 

For High Altitudes: Subtract 15% from the published HP to calculate effective HP. Example: 200 CHP (sea level) x 0.85 = 170 CHP. Use the 175 CHP row in the chart as your baseline.

 

For Sand Dunes or Large Tires (35”+): Subtract 8% from the published HP to calculate effective HP. Example: 200 CHP x 0.92 = 184 CHP. Use the 175 CHP row as your baseline.

 

For Tires 28” and Smaller: Add 8% to the published HP to calculate effective HP. Example: 200 CHP x 1.08 = 216 CHP. Use the 215 CHP row as your baseline.

 

For Launch Control: Install the High Engagement Primary Spring (sold separately). Add 2 thick magnets to the cam arms to compensate for increased spring pressure.
