That there is a DSP5 switch, you use it to cycle between 5 EFI live tunes which have been installed by the previous owner, i assume if the switch is on 5 thats the highest horsepower tune and 1 could be stock or modified stick tune. Hope that helps

Call or email the website on the switch with your VIN. They may be able to tell you what tunes are loaded, and you can go from there.....

Won't necessarily work like that. But it's worth a shot. I've put a lot of switches in that say duramax tuner on the sticker, and I don't use their tunes.

However worth a shot.
