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.  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.

Unitronic has developed corresponding Stage 2+ Performance Software for use with its Bolt-On Supercharger Pulley Upgrade to provide its users with an increase in maximum power!
