Any company has TCU tune for S550/S600 or Airmatic Tuning for S550?
I have been trying to do some research but cant get anything solid.
Does anyone know if there are TCU software upgrades from any tuner for 07+ S550 or S600?
I like my car allot (S550) next year would like to get S600. The problem im having is the adapting granny shifting trans. After taking it easy for 10 minutes it doesn't want to downshift when trying to get to faster lane. Almost had few cars rear-end me because my car just doesn't want to pick up speed and takes too long to downshift, if at all.
And im afraid even after ECU tune and intercooler upgrades S600 will be the same no matter how much power i get. Now dont think there is something wrong with it. If i drive aggressively it performs like an AMG, but i cant drive like that all the time. I drive low key most of the time, it goes in to granny mode and when i need it to respond quickly it just doesn't want to listen.
Secondly, has anyone tried doing some tuning on airmatic? perhaps making it a bit more active around corners? I would think lowering the inner side during cornering would help handling quite a bit.
i guess not needed on S600 with ABC 
Anyone with any info would be greatly appreciated.
Thanks
