A friend of mine has an 08 6.4 and has been complaining about high EGTs and terrible gas mileage since he bought it. He says the RPMs seem high also, as the truck stays at or above 1800 rpm at any speed less than interstate speeds. Has has the DPF delete and that is his only mod. The truck came with an Edge Juice programmer on the dash. He bought an H & S XRT Pro for the delete tune also. He was told he could leave the EDGE on "stock" power and use it as a gauge display. He runs the tunes from the H & S. Is this causing him problems? I've read on 6.0 forums that the edge tuners are bad news for them. Does that apply to 6.4's also?
