All highway.....cruise set at 70......which setting will be best for mileage?

I was thinking it would be the hot one (150) due to the timing change being more severe, but what do you guys think?

When I had my Stoopid box and I ran it most of the time on the 150 setting and it ran great and the mileage was pretty good as well..

under normal driving the most hp is the best..more power and you dont lose any mpg and you may gain some. i run my ppe on hot all the time and still get 16 city not sure what highway is havent had a chance to try it but im sure it wil be at least 20

I am going to move this to the electronics section...

I run mine on the 150 setting. If I run the 200+ setting I don't get as good of milage just cruising down the road. The 150 setting is usually good for a couple MPG over stock just cruising. (24 compared to 22)

That is what I was getting. Usually around 22 ish sometimes more..
