Hey Mayfiar!! Experiment, try the different settings ...but ya gottamaintain the same driving habits for all settings. I have the diablosport I run the extreme and foundit gets methe best mileage.. go figure! There is a setting for economy/performance which is suppose to get the better mileage. Some people are reporting better mileage in the "tow" setting.... comes down to driver habits, what mods under the hood and outside the truck ie. bumpers, fender flares, tires, lift kit..... with my mods seems extreme works best for me. as for towing, I tried through the mountains, with 10,000lb TT on tow stting was good for keeping EGTs down on hill climbs, but mileage wasn't anything to brag about.

You guys are getting incredible mileage. I just posted a thread to find out why I am only getting 10.5 city.
In a 2006 QC, CTD, long bed, 4x4 with 10000 miles bought brand new, with no mods as of yet.

That's what I'm doing now.

Right now I'm driving on level 2 with a boost setting on 3. If that doesn't help, then I think I'll bump my boost seting up 1 to level 4. then to 5 ...ect.

It's going to be a long haul test to find which is right for me, but eventually I'll find it. I'm just going to record my mileage on each setting and take it from there. I hope and pray that somewhere in that Edge is a setting that get's me better than stock fuel mileage.

I just sold my '92 dually, 2wd, 5-speed, 3.50 gear? In july I drove it from Detroit to Louisiana and back. At 70-75 mph, using Drews brew, I got 18-19 mpg. I just started using the "brew" before this trip. This was the 1st long trip I took it on, without pulling a trailer, so don't have prior data, but I'm sure the "brew" helped. It definitly fan quieter and seemed smoother.
