If I ONLY have a single tune (30hp), do the switch functions (0-5) on the MM3 even have a function?
The reason I ask is If one of those switch positions gets selected, would it change anything?
I was wondering if the ECM should now be reflashed.

You'll likely have a stock option 0 or 1, which will be your 30hp mode.
The others have no functions until you buy the additional tunes for the power tabs.

Okay, thanks!
I just previously wrote the custom file into ECM and let her eat.
I assumed the switch positions didn’t have a function, and the ECM ran off the custom file.
The thought that I’ve potentially just been rolling around in “stock for the last 60k miles is funny.
I agree; my understanding is with a single tune programmed into the PCM, you will be in that tune regardless of the switch position or if you remove the MM3 completely.
