I've recently replaced my M2C top mount intercooler and added a bottle to both my intercooler cooling system and engine cooling system. There is no issue with the factory cooling system and hitting temperature targets of the thermostats. When used with oe coolant and distilled water I can verify that there will be no issue.
When used in any other manner like a pure distilled water solution with only water wetter as an additive I cannot comment.

Yeah, that is along the lines of what I just posted. There will be no issue with ww and coolant because oe coolant will supersede what ww can accomplish as an additive in an s55. OP was asking whether or not if he should add ww and just water vrs using oe coolant.
Curious, why are you adding ww to your M2C’s coolant?
Are you overheating? Track?
