 Product Description

*TURBOCHARGER KIT PRICE IS $2999.00 with APR customer loyalty discount for existing Stage 1 and Stage 2 owners.


APR has developed an excellent entry level turbocharger upgrade for the 2.0 TFSI VL engine by incorporating the OEM turbocharger
assembly from the Audi S3 and coupling it with APR's expertly recalibrated engine management upgrade. APR's Engineering Team
has developed a powerful and reliable turbocharger upgrade that maintains OEM engine bay appearance and offers up to 155 hp
and 139 lb ft of torque
over the OEM power output of the 2.0 TFSI.

Reliability, drivability, stealth and enhanced performance that cannot be bested are the highlights of APR's newest OEM-component
based conversion package.

APR's engineers have expertly recalibrated the engine management system to allow for nearly flat torque delivery, which results in a
smooth linear pull throughout the power band. Keeping the track enthusiast in mind, this conversion package will not result in
overpowering of the driveline but will allow for smooth acceleration to easily maintain control while cornering.

The Borg Warner K04 turbocharger selected by VAG engineers is perfectly sized for the 2.0 liters of displacement to allow for stout
horsepower numbers as the RPMs increase with no dramatic fall off as redline approaches. This ensures plenty of power in the high
RPMs for continued acceleration in the straights and positioning at the healthiest portion of the power band after corner exit.

Optional OEM Exhaust Compatibility:

While a full exhaust is recommended for maximum power, If you're in a situation where running a high flow exhaust is not permissable,
APR has also developed software specificly to use with your OEM Exhaust system. You may switch between high flow exhaust software
or OEM exhaust software free of charge any time you alter your exhaust system.

APR EMCS Programs & Features:

Featuring APR's Patented EMCS program switching functionality and DirectPort Programming, APR's Engine Management Calibration for this
conversion package allows for a range of Octane and situation specific calibrations to be installed simultaneously on your vehicle's ECU. These
programs and features are able to be cycled through via your existing factory cruise control and activated in less than 20 seconds.

Program Switching:  Program switching allows the user to cycle through up to four different engine calibrations and operating modes all without
the need for external hardware.

Stock Mode:  By selecting stock mode, the ECU calibration is reset to the factory calibration. The engine will run exactly as it did before
purchasing APR software.

APR Performance Modes:  APR's octane-specific calibrations are available for various premium and race fuels around the world. Each
performance mode is a completely new calibration, altered specifically for the characteristics of the fuel quality selected.

Valet Mode:  APR's Valet Mode protects your vehicle from becoming an expensive toy for unauthorized individuals. By enabling Valet Mode, the
vehicle's performance is extremely limited. Launch control is uneventful, the vehicles top speed is limited to roughly 40 MPH and the engine's
redline is reduced to nearly 5,000 RPM!

Fault Code Erase: Fault code erase allows the user to erase and reset engine related trouble codes and ECU adaptation data without using a
specialty tool.

Security Lockout:  Security lockout prevents unauthorized individuals from using APR's EMCS functionality. When enabled, APR's EMCS features
will appear completely invisible until a user specified 2 to 4-digit security code is entered.

Anti-Theft:  When activated, Anti-Theft prevents the engine from starting even if the factory key is used. The vehicle will be completely immobilized
until a user specified 2 to 4-digit security code is entered.
