Hey everyone and thanks for your time. I recently have started to mod my 2000 F550. Looking to get the best mileage i can and i think im doing alright but would like to know what i am forgetting or missing out on. To start with the truck is an auto 4x4 dually with 110k on it. The killer is that i am turning 4.88's so fuel mileage is bad.
So far I have a f6 chip from dp tuner(modified stock, high idle, drive through, 80 econ, 140 extreme, 140 aggressive, lope idle, 60 tow and 40 tow), have the adrenaline HPOP, driven diesel regulated return bowl delete with post filter, 160cc stage one single shots, 4" turbo back exhaust w/ muffler, beans upgraded IDM, 6637, banks compressor wheel in the turbo(still running wastegate), CCV mod, stancor gpr mod, marinco block heater mod. I have boost, trans temp, fuel pressure, and pyro gauges. am i missing out on any goodies?
