APR News

APR is pleased to announce new enhancements to our entire B8 A4, A5 & Q5 2.0 TFSI AVL software lineup!


With over half a decade of development poured into this platform, APR’s Engineers are pleased to deliver several free upgrades to our existing customers. APR Stage I, Stage II and our K04 Turbocharger ECU upgrades are now revised with our new calibration strategies designed to produce a fantastic driving experience with more power and torque on tap!

APR’s calibration experts spent months working with the various ECU, hardware and octane configurations to deliver a driving experience second to none. Major improvements were made to the way the throttle behaves, leaving the driver to feel more connected to the vehicle than ever before. With control and response maximized, APR’s engineers set out to increase power while keeping factory comforts in mind during part throttle driving. Engine load, valve lift, cam phasing and boost levels were all optimized to ensure the engine was breathing as freely as possible for maximum output. Ignition, lambda and other aspects of the direct injection fueling system were tweaked to raise and refine power further. The end result is a fantastic leap in performance and response that wakes up the engine sooner in the RPM band and carries horsepower and torque further towards redline.
