Representing the ultimate upgrade for the 3.0 TFSI, APR’s Stage II+ Ultracharger Software is for use with the APR's Ultracharger Throttle Body and APR's Supercharger Drive and Crank Pulley upgrades. This stage is compatible with an upgraded APR Intake System, exhaust systems, APR Supercharger Cooling System and other small modifications, all without requiring any further modification to the ECU.
The system produces an astonishing 478-542 HP with 426-472 FT-LBS of torque. Gains as high as 133-196 HP and 97-143 FT-LBS of torque are available throughout the power band. The software was designed for use with the Ultracharger’s included NGK Iridium IX BKR9EIX spark plugs and an upgraded APR Supercharger Cooling System. IAT’s must be below 75c to achieve the advertised power figures. An APR Intake System is highly recommended and required to meet the advertised power figures. Finally, at these power levels, APR does not recommend use of the factory catalyst. Please note, transmission software is required to achieve power figures past the factory redline.
