XperTune Performance Software
XperTune performance software for the Porsche 991.2 GT2 RS (2018), a hybrid tuning method combining handheld OBD-II flashing with the ability to revert to stock at any time, rather than a traditional ECU removal and bench flash. Reprograms sensor inputs, air/fuel ratios and boost pressure, with maps available for a stock car or one already fitted with cat bypass pipes, sport cats, a full exhaust or upgraded turbos. On its own the tune adds roughly 60hp and 85 lb-ft of torque; paired with Fabspeed's sport catalytic converters it reached 75whp at 7200rpm and 108 lb-ft at 3200rpm, and paired with cat bypass or competition race pipes it reached 113whp at 6400-6500rpm and 125-130 lb-ft of torque, along with a noticeable increase in turbo spool and throttle response.
