Recently, Tom at tpc contacted me to try one out. Needless to say I took him up on his generous offer.
Is it the Holy Grail, best thing since sliced bread?? No, but it does 'fix' a lot of the 997.1 woes. Background, I have a lot of experience with 997.1 turbos street and track for almost ten years now, owned 4.
When I popped the box in, really only takes 5 min, differences were very noticeable. I immediately recognized the ride as my 997.2tts, but better. Porsche made the .2 more compliant by modifying the pasm control unit. Tpc injects steroids.
Tpc does to factory Porsche what Stewart-Haas does to a factory Chevy. The advantage of Grand Am Rolex racers vs standard tuners IMO.
The factory pasm unit really only uses 15% of the shocks capability, all or none. The dsc manages all 4 shocks independently in real time. The result is improved compliance.
Mode one is like a tuned 997.2tts, much smoother and more compliant. Mode 2 is a little stiffer, mode 3 even more so. All are better than stock. The handling is improved over a rough road big time, a lot less extra movement and sloppiness. Flashing lights are a non issue.
IMO, the dsc box is a big improvement for the stock suspension. It cleans it up and takes all the slop out. The oem with the box is superior to bilstein damntronics in every respect, and probably any street/track coil over that removes the pasm. It levels the playing field with gt cars on the track I would imagine. I can't wait to try it on a high speed track like Watkins glen.
Not the Holy Grail, but well worth it IMO.

Quadcammer,

I am sorry to hear you experience with DSC is not a positive as other users. May I suggest sending your unit back to us. I will personally test this unit in a bone stock low mileage 997.1TT. If for whatever reason it doesn't perform as intended I will gladly replace the unit with a new one that is tested. Please PM me to make the arrangement.

Tom

Just took the DSC box out.

Now, maybe I'm getting old, but on the crappy roads in northern NJ, the stock suspension box is simply much much more comfortable. Yes, its bouncy and a bit wallowy, but for day to day driving, I prefer it.

Clearly sport mode is rock hard, but for good driving on mountain roads, it should be fine.

Unless there is some defect with this unit, it will be up for sale soon.
