I just installed the TPC DSC unit. I have a 997.1 so I had to install the accelerator unit deal as well. I learned to solder in the process. The folks at TPC were very helpful and walked me through the process as I am not that great at mechanical or electrical work.

I fired up the car and the PSM error message came on but soon went away and hasn't came back. I'm still playing around with the settings so I don't have a full review yet. I did notice that the car does not lurch in the front when you gun it. Just straight forward. There also never seems to be a lean in the car. It's like you stay in one spot and the scenery changes. So far it feels much more precise and controlled. I can't wait until it dries up and I can get into the corners more. I also have a track day coming up so I hope to update this thread.

Questions let me know. Also feel free to comment on your experiences. I would be curious about your experiences.
