Hello,
I'm unsure if my switch is going bad or if something is going on with my ECM, but I have owned my truck for about 3 years and about 5 times it has gone from stock (I'm guessing. The truck had EFI Live on it when I bought it) to lope tune or whatever position 5 is called. Truck is a 2002 LB7. I do not know too much about the setting, was told 1 is stock, 2 is a little more, 3 is a lot of bit more, dont use 4 due to stock tranny, and 5 is a low tune it seems. Causes the truck to sound almost like it has an aggressive cam in it. Any help would be appreciated.

You will need to connect to ECM to see what setting its seeing.
Or buy a new switch and try it.
