Porsche 997.1 Turbo GIAC Performance Tiptronic Transmission Software Upgrade
GIAC
GIAC transmission software for the 997.1 Turbo offers a variety of benefits, including:
- Faster shift speeds
- Raised clamping pressure for higher torque capacities
- Raised shift points
For those with highly modified Tiptronic Turbos, the GIAC software will allow you to use the full powerband (rather than be limited by the low factory shift points).
