SharkWerks and Evolution Motorsports are running a promotion until the end of December: 20% off the price of EVOMSit software tuning for all models.

EVOMSit software adds horsepower and torque to stock and modified Porsches, adds Sport Pedal functionality for better throttle response, and will not give check engine lights or warning codes. Dyno charts are available for each model that was live tuned, with the whole process outlined in detail on our web site.

Here's a video showing the tuning in action (skip about half-way through), including the live emulator process:

Nice, I would do that yesterday if I had a P/F/L-car.
