My apologies, PowerstrockedSC. To my surprise, there is very little in the 6.0 forums on this site about the BB mod.
Countryboy07 hit the nail on the head. You pull the four screws that hold the regulator cover to the side of the fuel filter house. When the cover comes loose, be careful not to lose the brass cup, the spring, or the plastic air bleed fitting. Place a BB in the brass cup and button everything back up again. This adds about 10 - 12 psi of pressure.
So long as your pressures don't drop more than a few psi at WOT, your pump is still supplying the necessary flow at the higher pressure. If your pressures fall quite a bit at WOT after the mod, your pump is tired.
I have a feeling that your "guy who used to work for the ford dealer" is full of BS when he claims that a Ford engineer instructed him to stretch the regulator spring to eliminate repeated injector failings.
