Dyno Challenge

Test Horsepower and Torque


The DYNO Challenge is here and waiting to measure your truck's torque and horsepower. So, after all the power-adders and extras are installed, after all the tricks and tune-ups are finished on a participant truck's powertrain; the DYNO Challenge stands ready to reveal the results.

This is the "no brag-just the facts" validation that serves up honest, at-the-wheels...horsepower and torque numbers.
