Really not surprised at all ... they've gradually become less tolerant of modding and warranty claims over the last 5-6 years.
My E39, E60 and F10 (13') M5's were all tuned and never had any issues with any warranty work or any other crap.
With my 15' M5 I went Piggy as I started to see the writing on the wall and really wanted to avoid the whole headache of tuning and warranty issues.
19' MSC is stock w/ just a cat-back, wheels, suspension and CF bits.
