BigBlue99 is starting off with a positive reputation.
Anywhere from 9.5 to 11.5. Seems the wind plays a big role. I have been running 5startunes (93 & 87 performance) and stock still gets better fuel mileage consistantly. This is trended over a minimum of 5 tanks each tune. 93 performance is the worst but not that noticeable with ave. mpg at 10.1 and stock getting ave of 10.8.
