Stage 2+ Supercharger Pulley and Flash on an Audi S4

September 18, 2015

We had a customer stop by to install a Stage 2+ Supercharger Pulley and Flash on his 2012 Audi S4.  He started with the Stage 1+ which was an awesome add of 82 Hp, after a couple weeks he got the bug for more power and decided to move forward with the Stage 2+ Unitronic Tune and Pulley.  From Stock to Stage 2+ this modification adds a whopping 117 Hp and 60 lbft of torque to a  3.0t (Supercharged) Audi S4.

Here we have the graph Showing the power put out by the Stage 2+ on the Audi S4 3.0t Engine.



To perform this install we need to start by removing the front bumper of the vehicle to loosen the front end.  This gives us access to the supercharger pulley allowing us to fit the special tool required to remove the pulley from the supercharger.  While we are removing the S4 pulley we have the new performance pulley baking for 1 hr at 400 degrees.  The heating of the pulley allows the pulley to expand enough so you can mount the new pulley even with the extremely tight tolerances.

Once we have the new pulley and and belt installed it is time to put together the front end.  With the bumper reinstalled we flash the vehicle with the Stage 2+ Software, which really brings the Audi S4 3.0t engine to life.

    Hi Paul,
    Your videos are great for the DIYer’s like me. Thanks for those videos and also thank the others who helped you make them clear, interesting and complete. Can you please let me know if you can publish a video on removing the drivers window regulator, reinstall and adjust on a 2007 EOS? The regulator is out of warranty and the price for this at the dealer is just too much. Can’t afford it with a family to feed. Any help would be appreciated.
    Thank you,

      Im sorry we wont have a DIY on something like this. We would be glad to get you the part at a discount and you should consider a Bentley Manual to help with the install.
