My truck is a stock 03 2wd crew dually with 4:10 axle. I bought this truck with a bad engine to flip it. Then i drove it over 6 thousand miles so far and couldnt believe the mpgs i was getting as stock so i am keeping it. Most of my driving is 85% highway, going 60 on a calm day this truck is getting 20.3-21.6 mpg
per tank. At 70 mph i am getting 17.1-19.9 mpg
per tank. These are all hand calculated. I am almost scared to touch it but i am going to anyhow. I know this truck has the latest ficm/ecm updates from ford, they updated them when i had them program the ficm
when the engine was changed. Here are my plans as it stands:
Exhaust, muffler and particulate filter delete or full turbo back, what size?
gear vendors overdrive, i already have the unit i just need to get a correct adapter
switch to paddle mirrors i dont pull enclosed trailers anyhow just open car trailers
already have a hard tonneau cover installed
synthetic fluids with my next oil change
raise tire pressure to 80 psi
A tune but which one?
I dont plan to delete the egr
cooler at this time as its brand new along with the oil cooler when the engine was installed. i dont know if an egr
delete would help mpg's anyway.
I know i am forgetting a couple things but i am stuck in bed with pnemonia right now so this is helping get my mind off of it. Anyhow any input would be appreciated.
