APR Stage 2 Dual Pulley Upgrade for Audi S4
At the heart of the Rennology R2 Performance Package is a stage 2 Dual Pulley upgrade from APR. The ECU software upgrade and dual pulley combination produces a 135+ HP gain over stock and approx. 105 ft lbs of torque gain over the stock S4. Upgrading both the supercharger drive and crank pulleys results in the factory supercharger spinning approx. 26% faster than stock. This speed was chosen after extensive engine and chassis dyno testing by APR. This results in a significant bump in horsepower and torque across the entire RPM range. The APR engine performance software takes full advantage of the pulley modifications and makes more engine power by running more boost pressure, optimizing camshaft positions and timing, controlling valve lift actuation, adjusting the air/fuel ratio, and advancing ignition timing.
APR DL501 S Tronic TCU Upgrade
APR’s transmission software upgrade provides faster acceleration, quicker gear shifts combined with optimized shift points and smoother operation. The TCU upgrade also features launch control. 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. Under wide-open throttle, the transmission enters a different state of performance with shift maps optimized for power delivery. Manual and Tiptronic mode are tailored to the driver’s desired auto up/down shift preferences at the time of install. However, under part-throttle daily-driving the transmission remains calm and smooth.

SOUND LOUD & FAST
AWE Tuning Track Exhaust for Audi S4
AWE Tuning’s Track Edition Exhaust is crafted of T304 stainless and delivers noticeable volume and power gains. There are no valves or control systems for the Track Edition and this exhaust version is on the louder side all the time, with volume most pronounced in the mid rev range. A selection of tip sizes are available with the 102mm diamond black the preferred choice. Resonate downpipes keep the exhaust better behaved for daily use, but with the non-resonated downpipe option you can grab attention quickly!

APR Carbon Air Intake For Audi S4 3.0T
The APR Carbon Fiber Intake System increases performance primarily by improving airflow through the system while still proving adequate filtration. You can expect increased horsepower and torque throughout the power band and a more responsive feel from the throttle. Sounds from the engine and turbocharger are also enhanced.
H&R Sway Bars for Audi S4
The most commonly overlooked suspension upgrade is the sway bar. H&R Sway Bars are formed perfectly for each and every application and ultimately provide an unmatched level of precision fitment and performance. H&R Sway Bars are crafted from special 50CrV4 steel alloy and are the industry’s strongest and most durable. The sway bar cancels out body roll producing faster, flatter corners with a more predictable feel.
