Default Does Gryphon make a difference on a daily driver
Hi, I have an 08 F150 Screw with the 5.4L. I also have no mods and don't anticipate adding any mods. The reason I am looking at an Edge/Gryphon is to increase my mpg. On my last hiway trip I did about 400 miles in around a temperature of 0 degrees (F). I got about 15 MPG on that trip doing 75 mph. Will the Gryphon improve my mpg's at all if all I am doing is a constant 75 mph on cruise?


cheers
