Lvl 1 is likely what you have it on. That's valet mode and you are likely at %50 of stock.

Lvl 2 is mileage but really mileage won't change above level 2 if you keep your foot out of it.

Agreed probably a valet mode. Check into the owners manual and instructions there may be a pdf online to be sure. But you at least need to be able to hit overdrive to get somewhat decent mpgs where it’s not impossible but I don’t see overdrive kicking quite at 40. Most likely nothing but how is your fuel pressure I’ve seen faulty vp44s that have been given second lives strictly on hotter tunes but will be slow as a boat with low fuel pressure of the tunes. Probably nothing to worry about though
