ECU UPGRADES FOR AUDI, PORSCHE, & VOLKSWAGEN

APR’s ECU Upgrades are the best dollar-per-horsepower modification one can make to their Audi, Porsche, or Volkswagen. The upgrades are precisely engineered to dramatically increase your car’s horsepower and torque without compromising reliability. This makes for an exceptionally quicker and more exciting vehicle. APR optimizes the factory engine management system to take full advantage of the Audi, Porsche, and VV engine’s capabilities, without needing any end user adjustment. Once the ECU is unlocked, the software loads to the factory ECU through the OBD-II port, resulting in a clean and headache-free install. APR also offers tuning with a limited powertrain warranty, with purchase of APR Plus enhancement.

For the ultimate in performance upgrades for Audi, Porsche, and Volkswagen, we recommend purchasing APR stage I, II, and III performance packages if available. The performance packages can include APR engineered exhaust systems, intake systems, drivetrain upgrades and tuning,  and other products that are all engineered to work together for maximum performance.

Tuning and software upgrades for the ECU is often not enough for the power hungry soul. APR recognizes that in order to provide a complete automotive performance package for Audi, Porsche, and Volkswagen, they must engineer and build high quality parts to that can unleash the most horsepower reliably. APR offers stage kits which may include exhaust systems, intake systems, improved fuel system and injectors, better turbos or superchargers, and even engine internals that are all designed to work together with a matching ecu tune that will generate phenomenal power.  These parts may also be bought separately. The performance products from APR are designed and engineered for proper aesthetics, sound, power, proper fitment with function and style.
