Porsche Stage 2 — Prod: 98161866006 — A track-focused tune for the GT4, calibrated for a full performance exhaust system to maximize power and sound.
This is a high-performance Stage 2 tuning file for the track-focused Porsche Cayman GT4 (981), equipped with a Siemens/Continental SDI9 ECU. This calibration is designed for vehicles that have been mechanically upgraded with a full high-flow or decat exhaust system, from headers to tailpipes, to achieve the maximum possible performance from the naturally aspirated 3.8L flat-six engine.
This aggressive remap is engineered for the ultimate track day experience. We have extensively recalibrated the ignition timing, fuel maps, and VarioCam camshaft phasing to take full advantage of the free-flowing exhaust. The result is a significant increase in horsepower, a razor-sharp throttle response, and a breathtaking exhaust note that truly unleashes the sound of the GT4's motorsport-derived engine.
