Nope. If you know where to look in the ECM it does flip a bit that can't be reversed when a tune is installed. Most people don't know where to look, but it's big in the states for GM dealers to check cars every time they're at a dealer for modified software (whether it's been flashed back to stock or not, you can tell) - it's not policy here but you never know going forward.
Does that mean the Holden ECU updates through Holden flip the bit as well? Since technically.. that would be changing the calibration or operating system depending on updates available.
Commercial tuning software does exactly the same to that of Holdens, only difference is commercial uses a custom bootloader to read/write ECU contents.
