Tuning the DSC module, much like the OEM tuning the factory MRC, requires a non-trivial amount of telemetry on top of very skilled test driver feedback. You can get a setup to get great lap times at the expense of being enjoyable for the driver (for a variety of reasons), and vice versa.

When I tested the DSC module at Grattan, I had 4 pre-made tunes that all took different philosophical directions. I loaded each one for each session, chose the one that A) had the best lap times and B) had the best driver feedback, and then pushed forward on that path to improve both throughout the weekend. This had been preceded by weeks of street-tuning. In all I ended up with over 30 positive tune revisions before calling DSC and kindly asking for a refund, which they graciously did. At best I was able to match my OEM controller's lap time at the expense of the car feeling floaty and reactive. It wasn't fun to drive. The out-of-the-box tune put me 5 seconds off my usual pace. I am an instructor for Great Lakes Lotus Club and I have 13 years of HPDE experience on top of 9 years of national-level R/C racing, including a state championship.

Further proof that GM pretty much nailed the MRC tuning on the 1LE. DSC may make certain cars better (they get high marks in the Porsche world), but it doesn't seem to help the 6th Gen. Camaro's.
