The ultimate upgrade for the Audi R8 5.2L FSI V10 comes in the form of an APR ECU Upgrade that downloads an instant 59 extra horsepower and 53 ft-lb of torque to your engine control module. Your R8's engine performance will leapfrog the R8 GT and blow past Lamborghini Gallardo Superleggera territory, making this the best dollar per horsepower investment one can make. With 583 horsepower on tap, the R8 V10 screams all the way to redline and does so, as if intended by Audi, thanks to APR's strict adherence to OEM and Tier 1 Supplier specifications for engine component stress tolerances and performance specifications. The secret behind unlocking this level of power lies within the vehicle's ECU (Engine Control Unit) as it's heavily detuned, from the factory, to prevent the R8 V10 from stepping on the toes of other exotics in the VAG 5.2L FSI V10 lineup. Further tuning from APR's Engineering teams allow for faster acceleration and quicker throttle response through fine-tuning of the Bosch MED9 Engine Management System to extract smooth and reliable power every time you touch the throttle. Available in octane specific calibrations, the APR ECU upgrade is finely tuned for octanes around the world allowing you to take advantage of the fuel quality available in your area.

As always, APR's accessible via phone in the USA, M-F, 8:00 AM to 7:00 PM (CST) at +1 (334) 502-5181 or during the same business hours in the UK (GMT) at 0845 680 3527.

Thank you and Go APR!
