The APR Low Pressure Fuel Pump (LPFP) Upgrade is designed to ensure the low pressure fueling system is capable of delivering the proper volume of fuel from the fuel tank to the high pressure fueling system under high demand situations. Challenges to upgrading the LPFP: - Very little room for upgraded pump - OEM Pump requires a PWM signal - OEM pump controller overheats with high output pumps - Upgraded OEM pump controller not fully compatible - ECU modifications may be required - Secondary controllers often rely on physical boost signals The factory LPFP sits in a basket submerged in the vehicle's gas tank. The pump operates off of a pulse-width modulated (PWM) signal sent from the pump's control module, which is mapped in the ECU. As fueling demand increases and decrease, the PWM signal adjusts to send only the required amount of fuel through the pump. Unfortunately upgrading the LPFP is not a simple drop in task. The pump's factory enclosure presents some packaging constraints limiting clean expansion to a larger unit. Likewise, doing so often results in overheating and subsequent protective shut down of the factory control unit as it's operating outside of its intended design. This is even true when installing larger and expensive factory units like those found on high output vehicles, such as the Audi TT RS and RS3. Furthermore, upgrading the LPFP control module with the matching expensive higher output control units present other issues as the controller receives CAN messages from integrated vehicle componentry not common on vehicles requiring an upgraded LPFP. The APR Solution: - Inline fuel pump - Fuel pump controller with proper ECU CAN bus communication - Clean mounting brackets included - Direct bolt on with no software required - APR took a multi-step approach to solving the low pressure fueling system and is pleased to present a clean and accurately controlled solution for high horsepower applications. The APR LPFP System features a 255 LPH high-pressure inline fuel pump that sits between the HPFP and the factory LPFP. The included APR Auxiliary ECU sits on the factory CAN bus and receives critical operating information from the factory ECU to accurately control the pump. As fueling demands increase and decrease, the APR Auxiliary ECU controls output of the pump to deliver the desired volume of fuel to the HPFP. By connecting to the factory CAN bus, the APR Auxiliary ECU eliminate the need for less sophisticated and often problematic methods of controlling the upgraded pump. Because the pump only runs when needed, less power is consumed, fuel temperature is lower and noise, especially at idle, is essentially non-existent. Finally, with the fuel line disconnected, with the click of a button the APR Auxiliary ECU allows the user to quickly and easily empty the vehicle's fuel tank to make way for switching to higher octane fuels or for dry storage and transportation.

Building upon over a decade's worth of experience with turbocharged Audi and VW engines, including over half a decade with direct injected engines, APR's Engineers have taken the 2.0T to ground breaking levels of performance without compromise. APR is pleased to introduce the 2.0T Stage III GTX Turbocharger System. Producing 452 horsepower on 93 (R+M)/2 octane and over 485 HP in racing configurations with nearly no increase in turbocharger lag over the vehicle's factory setup, Stage III GTX places the 2.0T's accelerative performance in the same league as that of large V8 supercharged muscle cars and sub $400,000 exotic sports cars. Thanks to the vehicle's all-wheel drive system, power delivery is unlike anything previously experienced in standard form. As you hear a new exotic growl from your exhaust system, expect exhilarating g-force levels sure to put a huge grin on your face! Software included

APR is pleased to present the 2.0 TSI EA888 Gen 1 Stage III GTX Turbocharger System! In 2008, shortly after the worldwide release of the 2.0 TSI engine, Volkswagen of America commissioned APR to build the Stage III GT Turbocharger System for their SEMA concept cars. Successes of these concept cars lead to the first release of the APR Stage III Turbocharger System, based on the then available Garret GT turbocharger, and became a worldwide phenomenon. In the years since, APR has continued to work with VWoA, Volkswagen GmBH, VWVortex and BFGoodrich to deliver more concept cars for SEMA, Wörthersee in Austria, as well as other events around the world, while APR continued testing the latest in turbocharger technology. With the introduction of the Garret GTX2867R Turbocharger, APR has raised the bar further and redefined the standard by which the VAG community measures performance, reliability, drivability and quality. Gone are the days of compromise where low-end response meant excessive backpressure, compressor surge, and extremely limited top end performance. True to APR's mantra of Performance without Compromise the days of shredding tires on front wheel drive vehicles are rapidly disappearing thanks to the new Gold Standard in ECU torque management calibration strategies only APR can deliver. APR's endless pursuit of perfection has resulted in the most comprehensive 2.0 TSI turbocharger system in the world. The 2.0 TSI is completely transformed the second it meets an APR Stage III GTX Turbocharger System. Power immediately jumps to 423 horsepower with 387 ft-lbs. of torque on tap using 93 octane fuel on a completely stock and unmodified factory fueling system. Switching to APR's 100 octane race fuel mode, power shoots up to 458 horsepower with 409 ft-lbs. of torque all at the driver's command. This level of extreme performance is just a taste of the system's full performance capabilities. Software Included.
