Our Philosophy

The ECU reflash has been designed to provide smooth additional power while improving driveability over OEM mapping. Our tuning philosophy is to safely increase the HP and Torque without pushing it over the edge. Unlike other tuners, we use the dyno as a tuning tool to showcase the “delta” of the increase in performance – we don’t believe in chasing dyno numbers.
