i just wanted to make my engine a little more powerful if i could, not for speed, but to ensure that i don't tear up the engine trying to pull stuff that the truck can handle but not the engine...
If that's the concern I don't think it's a valid one.
Trying to get more power out of a given engine often adversely affects it's life expectancy. More power is more stress on the internal components, harder on the engine.
Getting what you have properly tuned and running well but still about stock is a good thing. Trying to make "extra" power is not necessarily a good idea if you want the engine to last.
As I said before gears are a weak engine's best friend when it comes to hard work. The truck will do most anything you ask of it if you take it easy and use low gears.
