A simple piggyback will just bump the boost up higher.
A 'smarter' piggyback will compare current boost signal and figure out how much to add based on pre-programmed values.


That being said... a 2020 M2CS is definitely tunable if built before 06/2020.
we are all just waiting for the tuners to crack the DME of the 06/2020+ cars so we can go back to tuning. Right now the only way is to get another ECU that is pre 2020. A piggy back is not nearly good enough as it doesn't change many of the parameters required from a good tune nor does it give the ability to delete the shit OPF filters that are on this car along with many other options.
