Any single tune can be configured to use any DSP5 Power Level. DSP5 Tuning is five power levels bundled into one switch on the fly tune where the driver has the ability to select the power level they desire with the ease of their steering wheel cruise controls. To change the predetermined mapping simply hold down the cruise cancel button for a few seconds turning off the cruise control and toggle the cruise control toggle (resume/increase speed) up or down to change your power level, up increases and down decreases. The glow plug indicator will blink the amount of times for the power level you are in. One flash correlates to the lowest power level and five flashes to the highest power level and zero flashes means you are in your stock power level.

30HP (Heavy Tow)
