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.
I just installed the Flex-a-lite 183kit on my 07 and I love it. I took a lot of weight of the engine with removal of the fan/clutch, and off the truck with removal of the fan shroud.:coolsmiley:
