Worked with Ben and got ACS springs, spacers (15/20) and the AC Schnitzer exhaust (which is awesome). (I'm getting OptiCoat soon so will post pics later).
Anyhow, on this topic, I went with Race Chip and drove it around for a week or so on the base setting S2=B. Admittedly, didn't feel different than stock, which is already a beast.
Then I bumped it to C, drove it a couple of weeks, then went to D, drove it around a few weeks, and finally, went to E last week. Frankly, it drives the same as it does with no RC installed. I've had to take it into the dealer a few times and each time I put the dummy plug on and I do not notice any difference between having the RC installed or not, and no difference between any of the settings. I'm considering the BMS, although Ben's experience is he saw no boost on his 6 series with the N63Tu.

How about when you drive in Eco Pro mode? My car was very sluggish before in Eco Pro, but with Race Chip it no longer an issue.
