FYI, the overhaed is no longer accurate with a box installed. Due to the fact that the box is "foolling" your truck into increasing rail preasure, the rest of your computer driven system doesnt know that. therefor the over head thinks your MPG is improved.



The disclaimer on these boxes says "You will get improved MPG with the same driving habits" Maybe you are the first to "Not change your driving habits".Im not saying that i'm tearing up the asphalt, but sometimes you just want to move a lil faster

No one with a box has yet to report any milage gains, no less that 15 percent

Keep HAND calculating your MPG, and report back to us.
