The dealership can always tell if they really want to dig. Unless you're trying to make a warranty claim on your tranny, they will most likely not even see/say anything.

There's really no need to flash back to stock if just going in for normal service. I believe you'll find that majority of folks leave their flash installed, even when taking it to the dealer.
