    • Gintani C7 Audi RS7 4.0 TFSI V8 91 octane pump gas tune results

      The Audi 4.0 TFSI powerplant is arguably the strongest tune only performer of the previous generation mid-size sport sedan class despite having the smallest displacement V8. Audi gave it a lot of headroom and they knew exactly what they were doing.


      Even on 91 octane pump fuel the car picks up massive gains. Excuse the tiny graph but torque increases by over 100 lb-ft at the wheels:


      Power goes from 507 awhp to 569. They also rev it out a bit more for a much stronger top end.

      Why still are not seeing turbo upgrades provided huge dividends on the platform is anyone's guess but Audi made sure the C7 RS6/RS7 had plenty of tuning headroom.
