The tuning involves a more aggressive fuel map, timing advance optimization for specific grades of fuel, and a more responsive accelerator pedal.
With software only, the 2010 GT3 went from 392 RWHP to 404 RWHP at the peak. The car gained about this much horsepower for most of its RPM range.
The car gained over 10 ft-lb of torque at its peak around 6600 RPM and more torque throughout the RPM range.
With the exhaust and software, the gains were higher, bringing it up to 414 RWHP at the peak (22 RWHP net gain), more torque at the peak, and a large gain in torque between 3700 and 5400 RPMs.
