After a couple of weeks running the DSC I am still in lurv...best $$ spent thus far. Next uo, RSS Tarmac kit and a roll bar...and then some new HREs and better rubber.
Oh, and the TechArt nose lift kit because I'm tired of scraping on dust mites

Just want to give some feedback on the DSC unit on my .1 GT3RS. Swapping the PSAM controller is quite easy, but splicing the 3-axis accelerometer is quite difficult for me because my rollbar's plate is partially covering the ECU plate screw, so I have to work with the exposed ECU wires in the limited space. It took me a couple of attempts to get it right.
My first road test was done on the Skyline in the bay area. Took Hwy 9 up to Hwy 35 to Alice, and drove back to 9 again to go to Scott's Valley. I use mode 1, the normal mode for this trip. The impression was remarkable, especially the ability of the stock suspension to soak up bumps at high speed. Before, although it was compliant, it was also a bit fuzzy/crashy. I felt the car almost glide over small bumps at high speed, but was stable without much body lean in corners. In fact, you could feel the outside stiffened up in corners, and it's the same while braking, the front end stiffened up under hard braking. On long sweepers I no longer feel the slight nervousness of the suspension as if the rear wants to come out, it is now rock solid and really inspire my confidence in the car.
Some time later I went to Sonoma Raceway to test it. Since it was damp in the morning, I drove with mode 1, and it handled quite well, compared to the stock PSAM's normal mode. After the track dried up, I noticed that at the esses from T7 to T9, the car's left-right transition felt a bit slower, so I switched to mode 2, and it decreases the transition delay. My confidence grew and I started to push a bit more, and at T4 I got the rear to rotate, but the feeling was smooth and progressive, and I fixed it by straightened my steering angle. Overall it feels like I have a completely new suspension.
I can't say how much time it has given me on the track because it was only my second time at Sonoma, and the first time was about 2 years ago and I was just starting to drive the car, so I am not driving the car to its limit yet, but still this has been one of the best mod I have ever done. No more 997.2 PSAM improvement envy for me.

I have that on my car if you want to 'experience' it before buying...

DSC on 911 turbo
I have a 2010 911 Turbo with the DSC. My car has the sports chrono with the PSS10 Bilstein Damptronic suspension. For me the ride on the street was harsh and bouncy in pasm base mode. In sport mode it was still bouncy but more harsh. I was worried this wasn't going to work out for the street or track.
I got the DSC about a month ago. Put on about 500 miles. Also put on 2 track days on it at Brainerd Intl Raceway. Comments on the street: nice, less bouncy, less harsh (still harsh but maybe feels more compliant). Before I could feel every expansion joint on the freeway. Now I can hear it plump plump over the expansion joints but I don't really feel it. So on the street I really like the more compliant ride. On the track in sport or sport plus mode (DSC gives you 3 suspension settings. Stock gives you two), I did not appreciate any bounciness. It felt very planted and compliant. In fact I did my personal best lap speed with this setup.
Worth the money for me and worked as advertised. I was going to take off the pss10s and put stock suspension back but this DSC made it tolerable on the street and pretty quick on the track with the pss10 suspension.

If you want to further improve both the compliance and performance without buying different shocks, get rid of the Bilstein main/tender springs and replace them with a longer single spring from Swift Springs and proper top plates. Such a conversion will also improve steering precision by replacing the stock rubber upper mount with spherical ball bearing top plates. I can help source these parts if you are interested.
