I typically get 21.6 mpg in my 2011 GT auto. Personally I think this is an astonishing number for a 5.0 litter v8. 2-3 Days later I noticed it was only getting 20.5 not a terrible decrease infact thats not the reason im asking, its more because of possible power decrease. The only thing I did between these Few days was remove the RAM air intake to make sure it was sealed well and replaced it immediately after and double checked to make sure it was tight. Also, will my 0-60 and 1/4 mile time be reduced?

Need more data.
~1mpg variation could be easily caused by almost any variable. Even a drop in temperature (which is happening in much of the northern hemisphere during this time of year) could cause that, even with the exact same driving cycle.
I'm not trying to downplay your concerns but I see nothing significant here.

Wow, I am not getting any where near where you guys with the GTs are. I run 91 non-ethanol and I am seeing 16.3. It is a mix of freeway and city driving. Could be the Trackey performance tune. But I do not see any difference when I run my Black key.

since I've been using 91octane (base tune) I've been seeing a lot better mileage.
The 28MPG is what i'm getting right now with my Base 17" wheels (Winter tires)
Yep, I just put them on this weekend
The 25.7 MPG average was my 19's.
Amazing numbers for a car of this calibre.
Those averages include some pulls here and there. It's impossible to drive this thing moderately all of the time
