Better fuel consumption and more power is what most tuners claim, but I didn't know it meant changing spark plugs more often?
Or is this 15-20K period different for an E92 M3? How often does the dealer change them when the car is still under warranty?
If I tune, does it mean I should change plugs in between dealer maintenances? If so, it might make me reconsider doing the tune...

It means the tune is pushing the maximum performance out of your engine, so even slight failures will be exacerbated, stuff that wouldn't be a big deal with the conservative stock settings.
Gotta pay to play, no harm in keeping your drivetrain in top shape
