DMS automotive (www.dmsautomotive.com ) has an ECU available increasing 997 turbo peak power from 480 to 540+. Furthermore, DMS can also engage Sport Chrono-equipped cars with the overboost function - which it also increases from a max of 501 lb ft to 535 lb ft+ - as a full time operation, rather than occurring in ten-second bursts. And these changes are undetectable by Porsche's diagnostic equipment.

Also, you buy the company's sports exhaust system, which consists of exhaust, cats and equal-length tubular manifolds, and get up to 580 bhp total.

I couldn't connect to the above website, but if someone in Europe can/does, please post the price of the modified ECU-packet if possible. Perhaps someone in this country may have such a mod available.

 

Its priced at 2,500 GBP.
