For Clients interested in upgrading their Audi S4 B8.5 3.0TFSI 333HP to the next level, Unitronic’s Supercharger Pulley Upgrade effectively rises boost levels by increasing the speed in which the supercharger spins at, 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 benefits. Unitronic has developed corresponding Stage 2+ Performance Software for use with its Supercharger Pulley Upgrade to provide increases of 101HP / 49LB-TQ over stock. Unitronic’s Stage 2+ Performance Software for the Audi S4 B8.5 3.0TFSI 333HP is available in two forms; with or without an Exhaust System Upgrade.
