MDM more intrusive after 1200 mile service?

A few hundred miles ago I had my 1200 mile service performed. I could have sworn that after the 1200 mile service I felt a power fall off when I was driving aggressively in MDM mode. After driving the car with DCS turned off it's not the power but maybe the MDM mode is more intrusive? Anyone else experience this or am I crazy?

Maybe, the car is making more power now (or not detuned) so mdm is just more active now with more power?

I'm not sure if its true but I heard car is slightly detuned until 1200 service?

Not true. If you followed the break in you kept it below 5500 rpm etc. once your car is broken in you are more inclined to go WOT and therefore are more likely to beak traction and instigate TC. Power is the same.

I'm going to have my MDM reprogrammed to EU settings. I'll post if that brings back the "original" MDM feeling I had before the 1200 mile service. Stay tuned.

I see your in Cali, but surely temperatures are still notably lower. As you get closer to that 45 degree mark the tires get noticeably harder and less grippy, inclining the TC system to kick on more often. This could be a substantial part of what you noticed. Report back when night time temperatures stay over 60 degrees!
