Trans rev match issue.

Hello and thanks for looking. I have a very odd issue I would like an opinion on. 2012 C63 MCT trans. Here is the issue. In manual mode paddle shifting from 4th down to 3, it will not rev match and has an aggressive downshift. In S+ mode, when I click it into paddle mode and down shift from 4-3 it rev matches perfectly. The issue is isolated to Manual mode only. What can be this issue?

do you currently have an ECU tune? if so which as it may be the cause of the issue you're dealing with.

My tuned 2012 has a hard downshift from 4th to 3rd when the trans is cold, while in M mode. When warm, the downshift is perfect.
