O.CT is a leader in reprogramming ECUs for more power via the OBD-II diagnostic interface. They have turned their expertise to the Porsche 911 Turbo and Turbo S, producing outputs ofup to 669 hp from the 3.8 liter horizontal-6.

This type of power required more than simply new programming. Two new variable geometry turbochargers (VGT), two modified air intakes, two near air coolers, a sports filer, and changes to the gearbox software are all part of the Stage 2 program.

The net result for the AWD 911 is a 0-62 mph time of 2.77 seconds and a top speed of 208 mph.
