best way to improve gas milage on 5.4L?
Who dug this one up Jimbo ?? 
Actually, adding a blower CAN net you better mpg's. But, -it can also keep you at the pumps, -if you get carried away.
Built 5.4L's can net as much as 16 mpg's; from what I've read.

I don't know, but i had talked **** to someone and then realized the thread was old as hell and they hadn't been on in months so i quickly edited to that worthless response you see now

Actually that's pretty good. Maybe you should do that more often ?

Or maybe I should take a few pointers, - blunt and to the point pointers.
If i start being helpful 100% of the time then what good is that to me?
screw all yal, i'll stay worthless with a 10% chance of something useful
It varies. The downstreams can last the life of the truck. Upstreams... depends on the engine condition. Even then, they normally last a long time. My upstreams were original when one went out at 120k.
Most of all, self gratification. You have to like what your doing.
So there's some value there.
thats with winter gas too. so maybe once i get used to it, ill see what it gets when i take a long trip.
