APR presents the 3.0 TFSI Supercharger Drive and Crank Pulley Upgrades.
APR’s Supercharger Drive and Crank Pulley Upgrades dramatically increase horsepower and torque by increasing the rotational speed of the factory supercharger. APR’s Stage II Pulley ECU Upgrade makes the necessary engine management adjustments to handle the increased supercharger speeds, and in turn allows the engine to create more power. The pulleys are sold separately, allowing for multiple levels of performance, each of which builds upon the other. Finally, when combined with APR’s Ultracharger Throttle Body Upgrade in a dual pulley setup, the system is alleviated of power robbing inlet restrictions, allowing the engine to achieve exciting new levels of performance!
Our previously released B9 A4 ECU Upgrade now includes support for the 2.0 TFSI as found in the new A4, A5, Q5 and Allroad! This upgrade dramatically increases output to 306-314 Horsepower with 367-388 FT-LBS of Torque, depending on fuel grade. Expect a dramatically quicker vehicle that gets even more powerful when adding our massive front mount intercooler. Get it at APR Dealers today!
