Can't wait to see the progress Ryan. Should play with some fender skirts!
I've gotten a combined-driving Tripminder-calculated 24.3mpg out of my box...with one trip hitting a record 26.5mpg just being more thoughtful of my driving habits. I haven't tried EOC or P&G, just mindful driving habits, and I gained 10-20% increase in mileage.
If my box can get those numbers, 30-35mpg in your areo with all your mods shouldn't be far off.
