Actually I believe if you have an older firmware there was some issue with getting the EDC to work through all parameters when lowered.
I remember reading this somewhere as part of a Technical bulletin for older cars to to be updated to newer software prior to dealership installing the MP HAS kit.
There won't be any lights on the dash if that worries you as many guys with 2015s on have lowered their car without updating software.
