2015 M6 power map?

[c0nfu$3d]

Am curious if anyone else experience a bog or low end power on a 2015 6. Wishing 1st and 2nd gear were just a bit taller, have to switch to manual in order to get the power I want. Is there any way to change the emissions map without dyno? Recommended on a lease?

Thanks.

What grade of gas are you using? The engine is very high compression (13-14:1 depending on country) and if the gas is lower octane the ignition timing will retard the timing to avoid detonation. Also, sport mode in the AT will be better in low end since it remains the throttle response.

I agree. The engine is wimpy around 1000 to 1200rpm.
Sports mode is my choice is I need to get offline quickly.
I have tried 89 and 91 octane, it makes small difference if any.
