Squeezing a few more mpg out of a mustang gt

Nice! Hilly terrain...did you put it in neutral on downgrades? Hilly terrain is good for mpg because it lets you pulse and glide at close to constant speed.

I did not. I was more focused on getting to my destination on time. I'm sure that could've got me to the 25 mpg mark on the trip

I think there's a flaw in my grille block, as I've yet to see coolant temps over 205. So either there's a 3rd source of air(possibly underneath the car), ford put an amazing cooling system in these cars, or my grille block is being forced backwards at speed

Also added about 40 pounds onto the back of the car(stock mufflers) so it'll be interesting to see how that hurts or helps my mpg

Well car is completely back to stock, except tires. Have a 120 mile(98% highway) round trip commute every Thursday night for the next 4 months. Gonna put my grille blocks back on, bump tires back up to 45 psi, and drive at 65; hopefully achieve 28 on the trips
