fuel pressure question
#1
hey i have a 99 4.8 with all the mods listed in my sig. i have been told that the fuel pressure can be raised or lowered in stock form. my question is, would i see any gain in performance if i raised the fuel pressure or just leave it at 38 psi? thanks for all the help.

Unless you have some way to see if you need more or less fuel I wouldn't mess with it.
You could always check and see if it helps by making a few runs on a dyno.
Fuel pressure at WOT should be in the range Hit Man X said.
