APR Ultracharged S4 Sets New 1/4th Mile Record!
APR B8 S4 11.1 Quarter Mile Pass with a 4,200 Feet DA!| 09/10/2015
APR S4 World Record: 11.1 with a +4,200 Density Altitude!
The race for a 10 second S4 3.0 TFSI just got a little more promising as APR sets an 11.1 @ 121.58 MPH in the quarter mile in extremely unfavorable conditions!
On July 30th, APR's S4 equipped with the upcoming Magnuson TVS1740 Supercharger System headed to Montgomery Motorsport Park in Alabama for a full day of endurance testing at the track with temperatures in the 100F's. Records were first set using Magnuson's off the shelf TVS1740 Supercharger System with APR's included 100-octane software, resulting in an 11.3@120 MPH on Michelin PSS tires.
As the day progressed, the conditioned worsened with temperatures reaching above 105F and the density altitude peaking above 4,200 feet. However, despite the terrible conditions, a new world record was achieved. APR's R&D team swapped the supplied pulley on the Magnuson TVS1740 to a new APR prototype upgrade, scheduled for release in the near future, and achieved an 11.1 @ 121.58 MPH pass!
"Given the extremely poor conditions (4200ft DA) our 11.1 second pass will hopefully lead to a 10 second pass as conditions improve here in Alabama. S Tronic calibration improvements, additional hardware changes (removing the catalysts), and further refinement of the overall package will only push the platform to a place we've all wanted it to go." Said Eric Urness, lead calibrator at APR.

APR Dl501 S4 & S5 S Tronic TCU Upgrade!| 05/14/2015
APR is pleased to present the ultimate transmission control unit (TCU) upgrade for the DL501 Gen 1, Gen 1.5 and Gen 2 S Tronic transmissions! APR's TCU upgrade is available for 3.0 TFSI platform vehicles and is conveniently flashed to the vehicle's TCU through the OBD-II port with user definable options selectable at the time of install.
APR's TCU upgrade goes beyond the overly simplistic norm of raising a few limiters, and offers a wide gamut of changes designed to completely enhance the driving experience. With an in-depth knowledge of the transmission's inner workings and control strategies, APR's engineers have improved many aspects of the transmission from accelerative performance to daily drivability, while also incorporating new features including several typically reserved for higher-end Audi Quattro GmbH RS models.
Depending on the driving scenario, APR's calibration experts have created multiple operating modes designed to deliver ideal performance for the given driving condition. When using launch control, the transmission enters a maximum acceleration mode designed to provide the fastest possible acceleration through a heightened application of torque, optimized shift points and shift strategies among other performance related enhancements. Under blistering, near wide-open throttle, the transmission enters a different state of performance with shift maps optimized for power delivery on vehicles with modified engine software. Manual and Tiptronic mode are tailor
