We've optimized turbocharger protection by monitoring shaft speed and respecting overspinning limits, excessive exhaust backpressure, and unstable pressure ratios. Low-speed pre-ignition (LSPI) protection prevents engine damage in high gears. Thermal management actively reduces power to prevent overheating of critical components and reduces power until your oil reaches the proper temperature. Fuel system optimization ensures safe, reliable operation within critical fuelling limits. The result? Massive power gains with the confidence that your engine and drivetrain are protected for the long haul.\u003c\/p\u003e\n\u003cp class=\"x_MsoNormal\"\u003e \u003c\/p\u003e\n\u003cp class=\"x_MsoNormal\"\u003e\u003cstrong\u003eEnhanced Driving Experience\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"x_MsoNormal\"\u003eWe didn't stop at raw power-APR's ECU upgrade enhances every aspect of your driving experience. To truly experience the sound of this engine we open the exhaust valves 100% above 3,000 RPM for sound and power delivery. Furthermore, we've calibrated a new light exhaust crackle that's like previous factory RS3 models. In park we additionally raised the standing rev limiter to 5,500 RPM, open the valves 100% during revving, and added the exhaust crackle.\u003c\/p\u003e\n\u003cp class=\"x_MsoNormal\"\u003e \u003c\/p\u003e\n\u003cp class=\"x_MsoNormal\"\u003eWe’ve also added left-foot braking and brake boosting for greater control on and off the track, while the speed limiter removal unleashes your car's full top-speed potential. The Auto Start\/Stop memory ensures your preferred setting is always ready, putting you in control every time you start the car.
