Ah, so thinking volume was a mistake, weight is correct. Thanks for explaining it to me.
I didn't have good testing conditions today. I do know that up to now my base MPG is 17. With the fan delete and the restriction removed, but no other mods, I have been getting 19.9mpg in mixed driving with a few red lights, town, some 55 and a good 65 run.
I'm hoping with the aerocap and a few other changes, I'll be up around 24-25 mpg, which means the F150 4x4 would be beating out the CX-7 for economy
Of course, I'll be working on the CX-7 too, so... If I can get that over 30mpg I'll be happy.
