OK so have all the mods in my sig. I have been watching my fuel pressure gauge and noticed I'm losing fuel pressure when i get on the truck hard. Its going down to 35 lbs. I added a fpr shim and it keeps my idle and low sped pressure much better... around 60-70 lbs. I know the mechanical pump needs switched out for a electric too. But what I was wondering was would a boost fooler help some? I know the MAP sensor is supposed to start telling the truck to defuel somewhere in the upper 20s in boost. Is getting a boost fooler worth it? Or is a pretty much useless mod?
