What "tune-up items" are needed?
I recently purchased a 1989 f-150 supercab 4x4 w/ 5.8l EFI, c6 tranny. This truck sat for about 1 year in a garage. I replaced the plugs, oil and filter, air filter, battery, coolant. What else would you reccomend? The truck has dual exhaust but you wouldn't know it from the sound. I want a deep rumble , loud enough to sound like a 351W truck should but I dont want to blow the neighbors away. Eventually, I'll want enough lift to run 33's or maybe 35's, and I want to gain some horses and improve the mpg's if all this is possible. What suggestions?

You could also change the Trans fluid and your fluid in your Differentials. Check your serpentine belt and all your hoses. Distriibutor. Plug wires. You could also drain the feul and change the feul filter like popa tim said. Also run a few bottles of feul injector cleaner through there.
When you lift the truck you can also change out all the bushings.

I'd also like to add a suggestion or two, making the list:
Tranny fluid flush & filter change
air filter
breather filter
PCV valve
oil & filter
plugs, dist. cap, rotor, plug wires
coolant flush
fuel filter
differential fluids
flush brake fluid (should be done every two years)
check belts, hoses, and vacuum lines
Inspect brakes on all four wheels
Flowmasters with a nice dual exhaust would sound sweet on a 351. Also consider headers. They'll help with performance and sound.
