2.7T S-line gasoline & Boost
I own Audi A6 2.7T S-line 265HP, 280lb-ft, shipped from USA. I use for it 91 AKI as i read on pump and that's the minimum octane rating i can use in it.Tomorrow i'm going to fill 94-95 AKI the same 98 Super European Unleaded.Acceleration feels quite fast, 0-60mp/h is about 6.9 7.0 seconds,but in my opinion on higher octane gasoline it would be a bit faster,How do you think will higher gasoline have an influence upon acceleration?? Can I somehow increase or decrease the turbo boost on 2.7T engine without chip modification??coz i've heard somewhere,but not sure in it's reality that i can regulate turbo boost.

I have not noticed any difference in performance or gas mileage when using 89, 91, or 93 octane gas. The higher octane just prevents pre-ignition (ping), and does not per se generate more power. As far as increasing boost, I believe the only way is to chip or re-program the ECU (which is what a chip essentially is). Your 0-100 kph times seem reasonable for the tip and a 3900 lb vehicle.
