Ok, the shimmed FPR, FPR mod and FPR shim are all the same, it consists of removing the Fuel Pressure Regulator (FPR) and placing a BB under the spring to increase fuel pressure (about 20psi). This will add a lil more HP and smooth the idle.

The 10k and EOT mods consist of inserting a resistor inline with a couple sensors to fool the computer and allow higher high oil pressure, Personally I didn't notice a big difference and the 10k made my truck idle pretty rough.

do you think its worth to shim fpr? and if it is, how do you do it

[fordnut85]

I think it is worth it since it's practically free and does help. Derik did a pretty good write up on it here....

EOT mod, Engine Oil Temp mod, I think?

the fpr shim did a help alot for me. it made my truck idle a whole lot better and it does seem to have a lil more power. it blows a lil less smoke too...which to me is a sign of improvment
