    • Bolt on B9 Audi RS5 with JB4 EA839 2.9 tune runs 11.2@122

      This is really what we wanted to see out of the RS5 out of the box. Speaking of which, adding the JB4 tuning box to the equation gets the B9 generation Audi RS5 performing much more like AudiBoost expected it to.


      Low 11's with just basic bolt ons:


      Just a JB4 on Map 5 with aftermarket downpipes and an intake.

        Spike is due to throttle closure so didn't get the flow. JB4 advantage is we can set per gear so we dialed the spike out using the boost per gear feature.
