I just filled up tonight. I drove 467.2 miles on 8.035 gallons of gas for an average of 58.1 MPG. Top speed was 71 MPH with an average moving speed of 49 MPH. The next three tanks will be done with "normal" cruise. However, I noticed with my new settings, it allows the car a wider range of speed since the sensativity is so low. I have Gain (Sensativity) at Extra Low. I've always had it at that setting, but I changed it from 4 Cylinder/Low to 8 Cylinder/Low. Before, the speed would only drop by 2-3 mph on hills. Now it drops as low as 9 mph on hills. Before on the longest steepest hill, instant MPG would drop to 34 mpg. Now it drops to 36 mpg. On moderate grades, it used to drop to around 40 mpg, now it drops to 48 mpg. Target speed will be 57 mph for the next three tanks and I'll see which is better. I think with the new settings, it most likely will be a toss up. With the previous 4 cylinder setting, I think the MAP mod would edge it out.
