Would it be possible to throw in a one-time free retune? I doubt anyone would intentionally ask the dealer to re-program the ECU and erase the aftermarket ECU tune. If it happens, it's probably just the dealer does it without even asking and notifying the owners. I think it would make people more confident to purchase the ECU re-programming.
