I bought a 4X4 quad cab with the 5.7. it has a k&n 77 intake, dual cherry bomb vortex and a bed cover. I would like to get more mpg out of it but I know that nothing I can do will significantly increase it. so I have opted to add more power while trying not to harm my fuel economy too much if at all I have heard good things about superchips and the diablo sport predator but I would like to get more advice on which chip people have the most success with. any suggestions? also looking into a flex-a-lite 183 e-fan.

Welcome! I had the Superchips and loved it on my 09.

What year is the truck?

The e-fan is likely the best bang for your buck to start it frees hp and reduces engine drag thus an mpg increase as long as you stay out of it.

Diablo sport is a good choice but I think superchips may have a little more stuff for that year.

I favor SC for just simple street tuning. DSP if you intend to use custom tuning.
