I don't know about the mpg gain yet but it did smooth out a "dead spot" this truck had when taking off. The sound it makes when you hit it was a nice surprise. I did have 2 problems and 1 issue. 1) no instructions at all came with the intake.(got it from your website) 2) the clamp the attaches the intake pipe to the manifold , was too small. You supply 3 large vlamps in your package, all the same size but that one was about an inch or more shy. issue: I called your tech support when I saw I had no instructions, left a message but never got a return call. Same as when I recently sent an email questioning the diffrence between 2 exhausts you make and again, no response.
