I had a query, after flashing the tune and settling on a configuration what happens when getting the vehicle serviced? When required do dealers/service providers alter the tune at all eg., apply software patches, restore defaults etc.?If they do how would

If the custom tune has been flashed in, they won't be able to write to your ECM as it will be locked. If you flash the car back to standard with the file we've supplied, then theywillbe able to write over the current calibration. Yes, they do alter the tune when required.It wouldn't, however very often the factory calibration revision is irrelevant to the aftermarket one we supply.
