By adding the DSP5 switch to your EFI Live tuned Duramax, you can change tunes on the fly. That means no more waiting on a programmer to download changes by reflashing the computer through the OBD2 port. With the installation of this switch, changing tunes is as easy as reaching over and turning a knob!
The tune in the PCM must be configured for the DSP maps. If you have tunes by another tuner, you will have to contact them to setup your tunes properly.
