Once I get mine all back together correctly, just yanked the egr system, I'm going to start computing the mileage.

It seems with the top off my runner I get less mpg.
I assumed taking the top off would lighten the load but it seems maybe the open back end is putting some drag resistance into the equasion.

Buying fabric to make a button on cover for the rear up to the back of the back seats to make it less resistive.
Plus a rag top to the roll bar may help.
May not.
Couldn't hurt
