bought a 2009 997.1 turbo 2 months ago.. certified i live in nj... did mostly every bolt on to the car with giac tune...wanted better handling and feel so decided to go with tpc....what are peoples thoughts on it? Decided to stay away from coilovers and springs car sits low already and putting forgestar f14 on it friday 19x8.5 19x12 if anything ill add maybe springs eibach in the future

 

Most "effective" handling mod I have, really felt the difference both in street and track.

I Also have HnR springs and some upper control arms and GMG sways. Didnt update to the 2 setting module as I like having 3 settings and the blinking does not bother me.

Just a few points off the top of me head:
- soft mode is much better adapting to road bumps/man holes, it felt the oem system just dumps the car back down, the tpc module I think braces the car much better which also means the car is more stable.
- Launches are much easier with less noticeable hopping
- Track duty was very good, hard braking is more stable and the body feels stable trailing into a 3rd gear corner. Gives more confidence so keep that in mind if you dont want to meet the traction limits

 

I really like mine. Makes a big difference and well worth the money. Put one on my Boxster Spyder also.

Nothing but rave reviews here! Great mod!

 

Many prior threads on this here and elsewhere FWIW. I have the earlier 3-mode box as well and it is absolutely a recommended mod; transformed the car. For many people I think it is enough, especially for "grand touring" and commuting uses. I am actually planning a more comprehensive suspension upgrade (PASM/DSC-compatible coilovers, springs, monoballs, sways, links...) as my usage is almost totally canyon roads now and probably some track events in the future. A custom-tuned DSC box (and custom Cobb ECU tune) will be part of my mod package.

The folks at TPC Racing /DSC are great to work with. The only reason I can think of to NOT do it are if you may go to a non-PASM compatible strut at some point; but even then I bet you could easily resell the DSC.

 

One of the best mods for the money, here to stay on my car!

 

Have one on my car.

Love it. Comfort for my daily commute into work is perfect indeed!
