But to save patch touching the ground i will be trying out a set of 185's instead of my 225 rears and 205 fronts. I will lose most of my height difference from stock but it may put me in a better rpm that makes power more easily.

Seems as I missed answering the question at hand. barely over 3,000rpm at 70-72mph.

Just wanted to update and let you guys know how things have been going. Second to the last tank on the highway I pulled off a 29.8mpg from my normal gas station in Wichita to the normal gas station in OKC. I was super stoked about that. There wasn't any EOC on that tank.
The last tank I drove around in Wichita and did a lot of EOC here in town for around 50 miles. Then I drove to OKC and ended up having to pop up my what I call my parachute headlights for 90 miles and made 26.8mpg. I was pretty excited about that considering I went through some heavy rain on the way down.
This last tank couldn't have been very good. I didn't do any of my hypermilling driving style. And I was playing around with my wife do some 5 gear rolls on the highway. I would guess it will be around 25mpg hwy.

I noticed that when I was doing a highway pull that my engine lid goes upward when unlatched. But I had an engine scoop on the driver side that was supposed to pull air into the bay. I decided that it was probably making turbulence within the engine bay. Since the air was coming into the bay from the side by the driver window and down into the bay, but the air under the car flows upwards out of the bay on the top. This had to make a lot more drag that I first thought. So I pulled it off and put the factory metal piece back on. We will see if this makes any difference. When talking about power people talk about how when they change performance parts that their "butt dyno" can tell a difference. So I will say my "butt roll resistance monitor" could tell that it rolls easier.

I've been thinking I am going to take my disc brakes off and have them ground flat again. I think that they may be dragging. Therefore making my engine off coasting not coasting very far. Let me know what you guys think about this.

Just filled up my tank last night. I am so stoked about my fuel consumption. This was with my newly deleted engine air snorkel. Only city driving and I got on it 3 times through 2 gears each time.
