Sorry for seeming I abandoned this thread.

Last thing I changed was removing the air ramp and basket, along with the cross bars on the roof rack. I ran a full tank of gas through the X same as my normal routine and saw no improvement in gas mileage. Got 18 mpg on that tank.

This is still doing the keep it below 65 mph, under 2,000 rpms while accelerating. Remember, best I've seen so far is 19 mpg doing this.

I went ahead and left it all off for now. This weekend I changed the air filter and fuel filter. Running a tank through it this week and will report back on my mpg.
