is to fully turn off the DSTC. ive done this tonight with my 06 R in comfort mode and its very driveable. i went over bumps and manhole covers that would make me feel like im going everywhere but im not with DSTC turned off. i havent tried it out on the really big ones here yet but where i drove tonight i noticed a definate improvement, it fealt like i was driving in sport mode actualy. has anyone noticed or tried this out?
