I've only been thru 2 tanks on the 4.4 version so far, both on level 3. 1st tank was all interstate w/ cruise set @70mph. I turned in 17.3, 2nd tank was 50/50 interstate/stop-n-go city traffic. That one dropped me down to 15.9.

I normally run a 75/25 mix of highway/city with my cruise set @ 65 for the highway part. With that and the previous software off mads site, I was getting around a 16.2-16.5.

I expect to see some better #'s once I get back in my routine and slow down. I still have the stock tires, too, I'm running about 2100 @ 65. If I could get that down to around 1800, I could probably get the mileage up quite a bit.

It does look like I gained some mpg w/4.4. I'll just have to keep testing to get a good idea of how much. I've bumped up to level 5 for the next few tanks, we'll see how that does.
