Stage 1 991.2 GT2 RS and Stage 2 Porsche 991.2 Turbo, Turbo S

GT2 RS Accessport Support

Nearly two months ago, we teased Porsche enthusiasts with 991.2 GT2RS tuning results.  Today, we are excited to announce the availability of Accessport tuning support for Porsche’s most powerful 911 ever.

Accessport for Porsche 911 991.2 Turbo / Turbo S / GT2RS The Accessport V3 is the world’s best selling, most flexible ECU upgrade solution for Porsche. Unlock power hidden within the vehicle by replacing conservative factory settings with more aggressive calibrations. Upgrade forever with off-the-shelf (OTS) calibrations for most bolt-on modifications. It’s the last engine management solution you’ll ever need.

Included Off The Shelf Maps are intended to be used on otherwise stock vehicles. The dyno graphs below show gains across the board for both 91 and 93 octane versions of our Stage 1 OTS Map.  On 91 octane fuel, we saw maximum gains of 15% HP and TQ and peak gains of 12% HP and 8% TQ to the wheels over stock.  Using 93 octane fuel, users can expect to see an additional 3% maximum gain, netting maximum increases of over 18% HP and TQ and peak gains of 14% HP and TQ to the wheels over the stock calibration.

991.2 Turbo and Turbo S Stage 2

Also new for the Porsche 991.2 platform are Stage2 Off The Shelf Maps for supported 911 Turbo and Turbo S models.  These maps are intended to be used on cars with upgraded exhaust systems containing high-flow catalytic converters and are otherwise stock.  The dyno charts below represent horsepower and torque gains over stock for the Turbo and Turbo S on both 91 and 93 octane fuel.

991.2 Turbo Stage 2 Power Gains

Base 911 Turbos see maximum gains of 34% HP and TQ to the wheels with peak gains of 12% HP and 28% TQ to the wheels when using 91 octane fuel.  With 93 octane in the tank, maximum gains jump to 38% HP and TQ to the wheels and peak gains increase to 18% HP and 32% TQ to the wheels.

991.2 Turbo S Stage 2 Power Gains

Since the Turbo S is equipped with slightly larger turbochargers, power output at Stage 2 is even more impressive! Maximum gains are 24% HP and TQ to the wheels and peak gains are 15% HP and 17% TQ to the wheels on 91 octane fuel.  Cars using 93 octane fuel will enjoy maximum gains of 27% HP and TQ to the wheels and peak gains of 19% HP and 26% TQ to the wheels.

More to come for 991.2 and 718 vehicles soon!
