Switch Tunes On-the-Fly

If you're running custom DSP5 tuning on your 2001–2004 LB7 Duramax, the DuramaxTuner 1101A020 DSP5 Switch is a must-have piece of the puzzle. This switch gives you full control over your tunes, letting you shift between five custom calibration files on the fly—no laptop, no re-flashing, just a quick turn of the dial. Whether you’re switching from a tow tune to a race tune or dialing things down for fuel economy, this setup gives you instant flexibility without ever popping the hood. The switch installs cleanly inside your cab and includes everything you need: the rotary knob, color-coded wires, mounting faceplate, protective conduit, and even the Allen key to secure it all. It’s designed specifically to work with the factory ECM on 2001–2004 GM 2500HD/3500HD trucks equipped with the LB7 engine, making it a perfect plug-and-play solution for DSP5-enabled tuning files. The blue and black faceplate adds a custom touch that stands out without looking out of place.
