Description

APR DTR8868 turbocharger systems are direct replacements for the EA839 3.0L turbo engine. These upgrades include matching software for various vehicles and mods, providing up to 620 hp (571 AWHP) and 422 lbs.-ft. of torque (572 AWT), depending on vehicle platform and fueling, all while keeping emissions components unmodified. The software supports premium pump fuel grades, race fuel grades, and even ethanol on the S4, S5, and SQ5 platforms with fueling upgrades. For dedicated race cars, the turbocharger is designed with plenty of headroom to go even further on your own.

The APR Stage 3 software is designed to avoid hard-spiking in the lower RPM band or running on the edge of what the factory rods and pistons should handle. Particular attention was paid toward component protections for exhaust gas temperature (EGT), back pressure safety (EMAP), turbocharger discharge temperatures, and fueling system capabilities. As rising exhaust gas temperatures require more fuel, the system will lower lambda to cool EGT without taxing the injection system with excessive on-times. Secondary protections will limit output for safety. The HPFP software helps increase headroom without over-driving the pressure to the injection system. The need for limiting power under extreme prolonged use (like tracking the vehicle), is greatly reduced, and the optional upgraded HPFP dramatically increases ethanol output.

Note: Specific software is required to use this system, and an upgrade from lower stage systems is included for various vehicles. Software compatibility must be checked before purchase as the software installs to your vehicle's factory ECU. Currently, software can only be installed by an authorized APR dealer. Software is available in two formats: for use with the stock HPFP or for use with the APR HPFP.
