Houston, we're ready for take off!

Get the highest performance per dollar modification and achieve incredible power gains (+60 WHP & +85 FT-LBS) without sacrificing driveability or reliability. Fabspeed Motorsport offers an alternative hybrid tuning method for vehicles equipped with latest generation of ECU's that traditionally require only bench flashing. No longer do you need to remove your ECU and mail it in for adjustments or to put it back to stock, just plug in the handheld tuner and simply flash your GT2 RS with the Fabspeed ExperTune or put it back to stock at anytime. The Handheld device interfaces with the OBD-II port on your vehicle and your computer to complete the tuning process. Performance ECU software upgrade improves horsepower, torque, and driving characteristics by reprogramming various sensor inputs, air/fuel ratios, and boost pressure (if applicable). Maps are available for completely stock cars, or for cars equipped with Cat bypass Pipes or Sport Cats, full exhaust systems, upgraded turbos, and more. 

You wouldn't believe all the power that's waiting to be unlocked in the 991.2 GT2 RS, Porsche left A LOT on the table. We've had ample time with a 2019 GT2 RS on our in-house Dynojet to unlock extra power on both stock vehicles and optimize performance with Fabspeed exhaust components.


  • Fits all Porsche 991.2 GT2 RS vehicles (2018+)     


  • +60 HP and +85 TQ


  • Sport Catalytic Converters with ECU Tune adds an insane 75 WHP at 7200 RPM and 108 FT/LBS of torque at 3200 RPM

  • Cat Bypass Pipes with ECU Tune adds an insane 113 WHP at 6400 RPM and 125 FT/LBS of torque at 3250 RPM

  • Competition Cat Bypass Race Pipes with ECU Tune adds an insane 113 WHP at 6500 RPM and 130 FT/LBS of torque at 3200 RPM

  • Incredible increase in turbo spool and throttle response


  • While a vehicle equipped with bolt-on upgrades will experience maximum gains as a result of the increased efficiency of the engine, great power gains can be made on a completely stock vehicle!  

  • You must have access to a PC / Windows computer (Mac OS not supported) to upload new tune files or reset back to stock with your Handheld device. 

  • The Handheld device "marries" with your vehicle and can only be used on one vehicle.

No need to send your ECU in to return to stock - simply use the Handheld to flash back, then to your Fabspeed ExperTune again at any point!
