Porsche’s next generation of it’s iconic 911, deemed the 992, spares no expense and in the uber-powerful Turbo S trim, the speed and power are simply unfathomable to most automotive enthusiasts. We’re known for getting even more performance out of the Porsche platform and that’s exactly what we did with the Porsche Turbo S using our in-house software, the AP3-POR-018 Accessport device, and our team of expert calibrators. And the best news is that customers in California are safe to install and cruise down the PCH because this Accessport and the associated tunes all have an Executive Order from CARB making it 50-state legal under D-660-161!

The Accessport V3 is the world’s best selling, most flexible ECU tuning solution for Porsche. Unlock power hidden within the vehicle by replacing conservative factory settings with more aggressive calibrations. Upgrade forever with included off-the-shelf (OTS) calibrations and the ability to custom tune for most bolt-on modifications via Accesstuner Pro. It’s the last engine management solution you’ll ever need. Installation takes just 20 minutes from the comfort of your own garage or driveway. Simply connect the included OBDII cable to your 992’s OBDII port under the steering column and follow intuitive the on-screen instructions.
Best of all, the Accessport and included Off The Shelf (OTS) Maps are covered by a C.A.R.B. EO and are legal to be used in all 50 states.

992 Turbo Power Gains
Our Stage 1 calibrations for the 992 Turbo are available for either 91 or 93 octane fuel and their increase over stock is truly astonishing. On 93 octane fuel, we are seeing 638 whp tuned compared to 557 whp stock and a mind-bending 655 wtq tuned compared to 562 wtq stock. This means you have an additional 93 lb-ft of torque on tap in the mid range along with an increase of 81 hp pulling you through the powerband.
