APR is pleased to present the B7 RS4 4.2L FSI V8 Stage III+ TVS1740 Supercharger System! Capable of up to 688hp & 562tq, it is sure to completely transform your RS4's performance and shock any muscle car that dares to line up next this this luxury sport sedan.
Since the release of the B7 RS4, Audi’s technological advances on RS models have grown dramatically. However, this often came along with the removal of traditional manual 6-speed transmissions many RS owners have grown to love. APR quickly realized the RS4 represented one of Audi’s last great performance sedans and chose to continue advancing the platform more than half a decade after the last RS4 rolled off the production line.
In the factory form, Audi’s older high revving FSI V8 leaves much to be desired compared to some of the latest technological advances brought forth by Quattro GmbH in recent years. The APR Stage III+ TVS1740 Supercharger System fills the void by adding an average of roughly 40% more horsepower and torque across the entire power band. The results are nothing short of amazing; taking the RS4 from 414 horsepower to 626 horsepower on pump fuel and 688 on race fuel without breaking a sweat! With more than 500 FT-LBS on tap thanks to the TVS1740’s positive displacement supercharger expect instant acceleration with absolutely no lag commonly associated with other forms of forced induction.
At the heart of the APR Stage III+ Supercharger System is Eaton’s latest Twin Vortices Series (TVS) supercharger unit, the TVS1740. The supercharger system is a positive displacement, roots style pump, utilizing Eaton’s lightweight, four-lobe 160 degree twisted rotors. Cast and assembled as a single, OEM-style-manifold and rotating group housing, the unit is quiet, compact, attractive, easy to install, and requires little to no extra maintenance to the unit itself.
The positive displacement supercharger offers power instantly as the throttle is pressed. Boost pressure builds with no perceived lag commonly associated with other types of forced induction, and provides a large increase in torque across the entire power band. Throttle control is linear and predictable and makes for an excellent driving experience both in daily driving and wide-open acceleration.
Since the supercharger does not compress air as it moves through the roots, it’s extremely efficient during light throttle and cruising situations. Unlike screw-type positive displacement superchargers that are always compressing, the TVS unit can internally bypass unwanted air, resulting in negligible parasitic loss during cruising and thus far greater fuel economy.
APR is pleased to present the ultimate ECU upgrade for the 2.0T & 1.8T generation 3, TSI EA888 engines. The ground-breaker to this upgrade is it can be port flashed through the vehicles OBD-II port for the initial programming, without ever physically touching the ECU, unlike most of it's TSI predecessors. This means less time and cost for install but also far less likely to have any future warranty concerns.
The Continental SIMOS 12 engine management system is responsible for proper operation of the engine during constantly changing environmental and load conditions. With built in compensational data for environmental variables and varying load conditions, the factory ECU is far more complex and intelligent than units found in other vehicle makes and marques.
APR’s Calibration Engineers spent months calibrating the engine management system, including many hours of in-house chassis dyno development. With a thorough understanding of the ECU’s torque structure, APR’s Calibration Engineers properly increased engine load to produce more power and torque from idle to redline. APR’s ECU Upgrade increases turbocharger boost pressure and optimizes cam timing, ignition timing, lambda and more to produce higher output. Using APR’s proprietary high-speed data logging suite, the calibration team closely monitored the effects of these changes to ensure a powerful ECU upgrade without derogating the engine’s drivability or reliability.
APR’s ECU Upgrade will provide an excellent leap in power and torque while retaining OEM knock control sensitivity and other built in safety features. The result is safely achieved power, optimized for various fuel grades found around the world.
Beyond power and torque enhancements, APR’s Calibration Engineers were able to increase the acceleration rate of the vehicle through other calibrations changes. Ignition delay is reduced resulting in a more responsive pedal without altering overall throttle sensitivity. Furthermore, drivability was greatly improved by reducing the throttle lag commonly noticed at slow speeds and while reapplying throttle after decelerating.
APR’s ECU upgrade increases the vehicle's top speed limiter for blistering sprints around the track or across the Autobahn without the speed limiter shutting down the fun!
Increased Fuel Economy:
APR’s Calibration Engineers paid close attention to several parameters directly related to fuel economy, especially while cruising at highway speeds. Depending on driving style and fuel quality, better miles per gallon may be achieved!
Left Foot Braking / Brake Boosting:
APR's Left Foot Braking feature allows more control over the vehicle’s throttle. The factory equipped vehicle's throttle input is disabled while pressing the accelerator and brake at the same time. Left Foot Braking, a common motorsport driving technique, allows the driver complete control over the vehicle’s throttle and braking system, which may give the vehicle the edge it needs at the track. As is with all features APR adds to the ECU, this feature may be removed upon request.
APR’s standard Stage I ECU Upgrade offers a large increase in low-end torque, which may overpower the factory clutch. While APR did not experience clutch slip at the advertised torque levels and even slightly higher, others may due to clutch health and driving style. APR recommends upgrading the factory unit, but has also created special software designed to deliver the same peak horsepower with a cap on low end torque. These specific files are available with various torque caps set lower than the standard Stage I ECU Upgrade.
*As this is a new ecu/engine combination not all ecu versions will have software available at time of release. Please contact us for pricing and availability.
Here at APTuning we want all of our customers to get their cars ready for end of winter and get your service done so you are good to go for the upcoming show season. Most of the enthusiasts are already planning trips but we all know there is nothing worse then your car leaving you sit on the side of the road because of procrastinating on preventive maintenance. See inside for info.
Therefore we are offering discounts on some specialized services. Service specials are for Timing belts, general service, and alignments, all prices include parts, labor and tax to complete the standard job.
For general service receive 10% off associated labor charges. Save money on everything from a simple oil change to a clutch replacement and everything in between. Simply mention you saw this post and get your discount!!
Timing Belt Service - Prices listed below - includes timing belt, tensioners, metal impeller water pump(where applicable), accessory belt, coolant, and taxes. By far the most procrastinated scheduled service on any vehicle is the timing belt. Usually due simply to the high costs of inflated dealer prices. This is an extremely important part of preventative maintenance that if fails will easily multiple the repair costs into the thousands of dollars. Factory interval schedules are usually between 90k-105k but we highly recommend replacement around 80k due to a lot of know failures before the factory specs.

A/C Service- $125 complete, includes check, vac test and recharge, freon, taxes. (covers most Audi/VW vehicles) Most of us have been there, first hot day of spring, sitting at red light and start feeling toasty. Turn the A/C on and gets marginally cool at best. Why wait to address the system once you realize it isn't working? Get it done now so when that day comes you can simply put the windows up and be comfortable.
Alignment Service - $70 Front Wheel, $100 All Wheel, includes labor, printout and taxes. (covers most Audi/VW vehicles) Alignment is probably once of the most overlooked services to be done to a car. Many people feel if the car goes straight the alignment is fine which is a terrible misconception. A car can drive straight but still have alignment issues which could negatively effect a cars handling or destroy tires. An incorrectly alignment can keep you from getting the performance your suspension or tires are capable of.
***We specialize in lowered cars and can do virtually any, no matter how low!!!
