GT cars are the pinnacle of Porsche’s line-up. Somehow, every generation the team in Stuttgart find a way to add power and capability to cars that are already more than 90% of us will ever need. Luckily, that still holds true for the newest 992 generation GT3. It’s all new 4.0L motor is a masterpiece and just sings all of the way to its 9000 RPM rev limiter. The aero and chassis updates have it producing levels of grip we would only expect out of its ‘RS’ big brother. That said, we can’t leave well enough alone. While tuning their turbocharged 911 counterparts can be much more gratifying with the mountains of torque available on tap, there is a certain level of accomplishment when extracting every bit of power from a high-revving naturally aspirated Porsche motor.

The simple DIY plug and play connection to the car’s engine management system via the OBDII port allows for any GT3 owner to apply improved engine calibrations to their favorite track weapon in a matter of minutes.
