Re: New truck to me.. 5.4 upgrades??
You won't get the HP gains from light modifications to a gas engine as you would a diesel. Not to say that there's nothing to be had, but a cold air intake and exhaust would help breathing. Running synthetic oils everywhere possible would be another, good cost alternative. Synthetics don't add HP, they free up HP that would have otherwise been lost to excessive friction caused by standard oil. This normally increases fuel economy in everyday driving. Unless you get into the engine and add major components, you won't 'feel' any difference with standard bolt on mods. Especially not on a 3 ton truck.
