This test compared a Volvo with a Power Box installed, the standard engine calibration and a full ECU remap. Wheel slip on the damp dyno rollers affected the first run, so the team repeated the pulls to check the comparison.

The graph in the video shows about 130 hp and 250 Nm in the standard configuration. With the Power Box, the result was approximately 144–146 hp and around 273 Nm. After ECU remapping, repeat runs showed about 183–185 hp and 340 Nm.

This test shows the result for one Volvo, not a universal comparison for every vehicle or Power Box device. Dyno conditions and the vehicle’s mechanical condition affect the readings.
