[QUOTE="golfer, post: 594717, member: 266"] negatron... my 6.4 is in the body shop (nothing major, someone hit the fender while I was parked)... once it get's back, cab's coming off, and the intake (as well as other parts) will be installed... I've thought about this a LOT... and aside from the (dirty) intake 'theory'...I think it's equally..and honestly MUCH more likely that the poor fuel economy is simply from these things running 10psi of boost tooling down the hwy... an equivalently powered (single turbo) 7.3L or 6.0L would be running less than 3-4psi if annnny under those same conditions.. lots of parasitic loss 'driving' a turbo, compressing the air, the pistons' working against that boost (and drive pressure)...to make what...70rwhp to run a steady state 75mph on flat ground?? if I have time before the cab get's yanked..I might start messing with the VGT controls in the MCC software...open those beetches up.
