This is a comprehensive Stage 2 tuning package for the Porsche 911 991.2 Carrera GTS, equipped with a Siemens/Continental SDI21 ECU. This package is designed for vehicles that have been mechanically upgraded with high-flow or decat downpipes and a performance intercooler to achieve maximum performance from the 3.0L twin-turbo flat-six engine.
The package provides ultimate flexibility with two separate Stage 2 files. The first is a pure performance tune, maximizing power and response for your modified hardware. The second file includes the same powerful Stage 2 calibration plus a software solution to disable the OPF/GPF systems, intended for dedicated track cars with a fully unrestricted exhaust system.
