Dyno and field tested, the Power Surge 6X will allow correction for humidity, temperature, air pressure, along with race fuels and motor modifications. The tuner adjusts in a matter of seconds in 6 zones, including an accelerator pump feature for more throttle snap response. The tuner can add or subtract fuel from the injection system. Conditions like rich or lean running, and stalling from flame-out at low revs can be corrected.
