Porsche 991.1 Turbo S Tuning - Genome Design

Porsche 991.1 Turbo S Tuning by Genome Design

Elevate your Porsche 911 experience with unmatched performance and precision. Our custom Turbo S ECU tuning delivers exhilarating power gains, advanced calibration options, and expert-level integration with the Siemens SDI21 engine management system.

Unlike generic tuning files, our remaps are developed in-house using our state-of-the-art 2000whp climate-controlled dyno cell, ensuring consistent, real-world results. This is performance tuning without compromise.

Tailored Porsche 991 Turbo Tuning

Every Porsche is different—your tune should be too. Our custom 991 Turbo tuning solutions are individually crafted to suit your specific vehicle, taking into account your unique engine setup and drivetrain configuration. This isn't a generic map—it's a fully bespoke performance calibration designed for optimal response, reliability, and driving enjoyment.

Our Stage 1 991 Turbo S tuning is carefully crafted to seamlessly integrate with your Porsche’s stock hardware. It significantly boosts power and torque across the entire rev range, while maintaining optimal heat management and fuelling adjustments, ensuring your car performs comfortably within the capabilities of the original cooling and exhaust systems.

With our in-depth expertise of the SDI21 control unit, we’re able to deliver a bespoke tune for each vehicle, enhancing overall power output, delivering a refined driving experience, and providing incredibly responsive throttle control.

Drivability and High-Performance changes

Our Stage 1 remap for the 991.1 Turbo S delivers substantial performance gains, boosting power to 620bhp and torque to 650lb-ft when paired with high-quality 99RON fuel, such as Shell V-Power. The revised torque curve is specially tuned for an exhilarating midrange response, providing impressive performance throughout the entire rev range. With meticulous attention to every aspect of this Turbo S remap, we ensure a refined driving experience that remains smooth and responsive. We’ve also fine-tuned the throttle mapping, offering a precise and natural pedal feel, perfectly aligned with the throttle body for exceptional control.

Fuel Grades & MPG

For the best possible results, we recommend using a minimum of 98RON fuel, such as Shell V-Power. This allows us to precisely adjust ignition timing and knock control settings, ensuring maximum power and torque output. While tuning can be done for lower fuel grades, performance figures may be impacted. By tuning your Turbo S to run on the correct fuel grade, we guarantee a consistent performance that meets our expected power levels every time.

991.1 Turbo S Additional Tuning Features:

Porsche PDK TCU Tuning

We highly recommend upgrading the PDK TCU tune alongside our Porsche 991 Turbo S tuning. This upgrade enhances torque limits, increases clutch clamping pressure, improves shift speeds, and optimises shift points for a smoother, more responsive driving experience.

Without a TCU tune, the engine’s torque demands can cause the gearbox to work under strain, potentially limiting torque output. While some tuners may offer this service, it’s not the ideal or safest way to tune your car. It’s akin to drastically increasing torque limits on a manual vehicle without upgrading the OEM clutch.

Given the immense torque generated by Turbo Porsches, we always recommend a PDK tune to ensure your gearbox performs at its best. Without this optimisation, the risk of microslip becomes inevitable, affecting overall performance and reliability.
