Anybody have any ideas why the manual rev matching falls short by a few 100 rpm? Being Porsche, there has to be a good reason!

you mean auto rev matching :-)

manual do you it, well manual !

most cases for mismatched rpms is user being too slow in changing gear, but not sure how you can notice 100rpm or why that would matter.

turn sport off and rev match yourself :-) or change gear faster in sports mode.

I think that you need to dump the clutch as soon as you engage the lower gear. If you do that it should work well. I have it on my M2. I ignore it, am more gentle on the down change and over ride the blip with a bang on the throttle.

Not an issue, just a curiosity. My BMW 440i rev matched perfectly - that's why I noticed.

The F4T is more responsive to throttle blips than the BMW, maybe I'm just too slow for it
