Ohio-based tuner Switzer Performance has unveiled a new tuning package for the Porsche 997 Turbo. The tuner worked on reprogramming the Porsche’s transmission control unit (TCU) software to increase the torque limits, but they needed more than that if they wanted to obtain a total of 700 HP.
Switzer disassembled, upgraded, and rebuilt the Tiptronic transmission to meet customer demands for higher hp projects. The first builds produced transmissions that were stronger and sharper than the factory unit, but not strong enough to contain Tym’s hard-hitting P800. So the tuner kept on working. They added more clutches to eliminate slippage, additional friction surfaces to ensure more efficient power delivery, a modified valve body to improve shift speed, and (last, but not least) another round of transmission programming which enabled the Tiptronic to have a tremendous boost in power and live up to its potential.
The result? A sprint from 0 to 60 mph in 2.8 seconds on standard tires and standard air pressure while running on pump gas. The price for the package is $7990.
