Quality APR Software

APR’s RS6/7 Turbo ECU Upgrade is designed for use with Audi’s high output RS6/7 4.0 TFSI turbochargers, which are a direct bolt on to the factory S6/7 4.0 TFSI Engine. This upgrade offers 634 HP and 671 FT-LBS of torque on 93 octane fuel and 707 HP and 714 FT-LBS of torque with race fuel! The substantial increase in power and torque comes with lightning fast response and smooth daily driving that transforms the vehicle into a new class of enjoyment!

APR’s Calibration Experts recalibrated the factory Bosch MED 17 engine management system to work seamlessly with the upgraded turbochargers, and offer a range of flexibility depending on vehicle modifications. Though the upgrade works well with with factory charge cooling, the ECU Upgrade is calibrated to take advantage of any cooling upgrades that are made. Additionally, the upgrade will work with the factory downpipes, though output will be less than advertised.

APR’s RS6/7 Turbo ECU Upgrade comes with all the benefits and features, including APR EMCS Program Switching and APR Mobile, as found on APR’s Stage I and II ECU Upgrades, and is conveniently flashed through the vehicle’s OBD-II port.

Endurance Testing

To make sure that our new turbo kit was properly making power on a consistent basis with no issues, we repeatedly tested a customer’s RS converted S6 at a private drag strip session. As you can see in the video below, our S6 has no problems keeping up with an already upgraded APR tuned RS7. With temps in the 90s and humidity of over 100%, our fastest time of 10.9 definitely proved that this kit makes a lot of power! In addition, at a 1/2 mile drag race event, both cars posted literally identical top speeds of 151.9244 mph!

So if you’ve been looking for that must have huge power increase for your S6 or S7, feel free to contact us to set up an appointment, you won’t regret it.
