HP Tuners Diesel Switches

Not Yet Reviewed

HP Tuners diesel switches let you power up from a stock calibration to one of five custom maps with the turn of a switch. These 6-position rotary switches feature knurled aluminum knob and position dial, and 5 ft. OBDII pass-through cable. With the optional OBDII port brackets (sold separately), the switch mounting possibilities in your truck's cabin are many, and for complete control and performance, pair your diesel switch with HP Tuners Switch on-the-Fly (sold separately).
