My basic thoughts before stepping into "performance land" is getting the truck entirely up to shape, inspect, and check everything!
Hoses, Belts, Plugs, Brakes, Vacuum Lines, Tires, Lights, Filters, Lubes, Oils.
Then go from there.
Not sure where you're at, but here in the southwest desert, I sure in hell don't wish getting caught with my pants down in 106+ degree heat, 50 miles out of town, with a blown coolant hose, or snapped Belt. And there I am, don't even have a darn bottle of water, and buzzards are flying. Yep, it's like that here, for sure nobody wishes to be SOL.
Look at all safety items, Tires, Brakes, Lights, Wipers.
Then move on to comfort items, cabin filters, detailing, paint, trim and interior care.
These costs of upkeep alone can tax a well paid man's salary.
Not sure what "performance" you're wishing to achieve? Usually all only make a vehicle burn even more gasoline. Is that something that has little consideration?
Lubricants-Fluids, check, and perhaps drain-swap all. Don't skimp, you often do get what you pay for. Batteries, another you don't wish to overlook.
As for performance, I like getting from point A to point B, with no problems-hassles. Forget about the fancy 4-prong or iridium plugs, save your money.
As for performance, a nice simple Hypertech Programmer will give you a few ponies, you'll be able to to tune engine parameters, speedo errors if going with different-larger tires in the future, speed limiter, shift points, and firmness, without making your vehicle seem like you have a 2000 horse blown engine under the hood.
