Hi therock,

For starters, I would suggest having him do the same basic mods that you've done to your truck, as the 4.6 responds to those same basic types of modifications as well as the 5.4 motor does.

Since he's already done the Superchip, then it's time for one of the airbox elimination kits, and a good cat-back exhaust. Then from there it's overdrive pulleys, headers, and converting over to electric cooling fans, for most people, and we'd advise going basically along those lines for your brother as well.

If you or your brother have any other questions, or would just like a little help mapping out a good plan of action based on how he's using his vehicle and what he really wants to achieve, please feel free to give us a call, ok?

Good luck!
