APR releases high boost pulley for Audi 3.0 TFSI Supercharged V6 (B8 S4, A7) +108 AWHP with tune
The new 3.0 TFSI supercharged V6 is becoming a popular Audi mod platform as Audi boosted motors often are. APR had an ECU tune available already for some time which was their Stage I upgrade. The pulley is their Stage 2 upgrade and to see the benefit it is best used in conjunction with the ECU tune otherwise the car will dump the excess boost. Gains with the ECU tune are very healthy at just over 100 horsepower at all four wheels, 117 AWHP with 100 octane.
