You shim the fuel release to allow for more pressure in the fuel rail. I dont think it helps much stock but when you add boxes it can help becaue it keeps the valve from opening untill a higher pressure is reached.

if you go to TS performance's website they have instructions on how to shim the fuel release when you install their mp-8

It is mainly a mod to accompany the MP-8

if you get the mp-8 it is a must....unless you dish out the extra cash for the plug but I don't think that it is recommended if you have other boxes on the truck like the edge juice w/att
