Switzer Performance Innovations (SPI), Ohio based tuner has revealed its creation over the German exotic Porsche 911 GT2. This time the tuner comes to increase the power of the extreme 911 up to 800hp (597kW) via twin-turbo kit. This power increasing needs adding in-house developed headers and sport exhaust system, a new intercooler package and custom GT30R turbochargers. Switzer also boasts that this is a truly bolt-on system because the factory ECU has been kept intact. Although there no performance released but the new Porsche 911 GT2 with 800hp should be faster than the stock.

SPI tuner also addressed its creation to make the driver easy to manage the cute monster Porsche 911 GT2. The modification is not only about big power but also how to manage. The power is designed to run with an efficient and linear power curve that makes it feel smooth. But to reach this goal, the modified Porsche 911 is required running on just regular 93 octane fuel.
