APR has developed a range of various stages of turbo upgrades for multiple Audi vehicles, suitable for each customer’s application. These upgrades vary in output from extreme track-ready performance to systems that offer a lightning fast response with smooth daily driving power that transforms your vehicle into a new class of enjoyment.

APR’s Engineers have spent countless hours testing to stay true to APR’s mantra of performance without compromise. Turbine inlet and A/R sizes are optimised in order to decrease turbocharger lag without negatively impacting peak power. Complementing the turbo’s lightning fast response characteristics is a newly developed anti-surge housing, which enables APR’s Calibration Engineers to increase the reliability of the system without limiting the area under the curve typically experienced during a top speed acceleration run.

Each turbocharger unit is assembled and clocked in-house at APR with the necessary brackets to ensure proper wastegate fitment and orientation. Each wastegate is then calibrated for precise operation and control to ensure seamless integration with the expertly recalibrated OEM engine management system.
