I'd like to avoid returning back to stock tune as it would take a while for the car to relearn the tune after servicing.

Thanks

No don't worry about it, unless they are planning on flashing something to the ecu like a reflash of some sort (which they will tell you beforehand) it's a non issue, if it's for warranty work in the future you can still run the tune as long as it's not something that involves the ECU directly otherwise flash to stock. The OFT roms are almost totally undetectable, to techstream for them it'll read as stock because the ecu isn't locked like ecutek roms.
