Our customer Walter just finished doing his VR Tuned ECU Flash on his 997.1 Carrera with us. The super clean yellow 997 with black accents is a perfect candidate for the VR Tuned ECU upgrade. The 997 Carrera whether the 3.6L or 3.8L benefits from the torque limiter raised, throttle response improved, mid range power increased, and pulls harder to redline with the speed limiter removed. On manual transmission cars we can even raise the rev limiter 500 rpm and raise the limits for the secondary O2 sensor on high flow or catless exhaust systems.
