For Clients interested in upgrading their vehicle equipped with the 3.0TFSI (CREC) engine, Unitronic's Bolt-On Supercharger Pulley Upgrade effectively raises boost levels by increasing the speed in which the supercharger spins, allowing for additional airflow to be ingested by the engine.

Unitronic has developed Stage 2+ Performance Software (sold separately) for use with its Bolt-On Supercharger Pulley Upgrade which helps produce up to 451HP / 388 LT-FT. Without a corresponding Software calibration to make use of the increased boost levels, the system will simply bleed off excessive boost resulting in no performance benefits.

Hardware Included
  • Unitronic Bolt-On Pulley
  • Installation Hardware
Required Software
  • Unitronic Stage 2+
