Should I remove the Mountune upgrage on my Ford Focus RS to achieve best residual value?

I'm about to take delivery of a brand new Ford Focus RS with the warranty approved Mountune upgrade. When I come to eventually sell, it do I need to remove the kit to achieve be the best residual value? In which case, should I ask the garage to keep the parts they have taken off to install the Mountune kit?

I don't predict residuals anyway, much less for a high performance car with enhanced performance.
