I also have an Edge for my F250 7.3 diesel. I got it for the tow level and was a little disappointed when all I really experienced was the quick change between gears. I recently programmed "Racing" and was extremely pleased with the change in acceleration AND increased mpg. From 18-19 to 21-22. I haven't towed at that level so glad to see several have. I expect to see a significant improvement in uphill towing. I also dropped it into Performance and, well, Racing is plenty for me. Edge is a fine product. I got the shroud and it matches dash almost perfectly.
