Re: 13 mpg!

Did you try cleaning the EBP sensor & tube? Sometime a clogged tube can result in crappy fuel milage. Here's the link:


But I'm not sure the edge will help with fuel mileage like a custom chip does...

Re: 13 mpg!

When my truck was stock I got 13 mpg unloaded and 11 towing around
11-13K of horse trailer. Somewhere in the middle of all of these mods I was able to get 16.5 mpg unloaded and 13 towing. Now I get around 14 all of the time. It doesn't matter weather I am loaded or not. When I am not loaded I drive pretty fast, freeway around 70-75. One of these days I will try and get my foot out of it and see what I can get. But then again I love to frive so may not get my foot out.
