I bought a Edge EZ for my dad's '03 6sp. I put it in set on level 1 since he tows a lot. I never put the boost elbow on. In the instructions is says the EZ performs fine without it. It the one TDR article they say that the turbo loses efficiency over 24psi. Should I put it on or leave it off. I don't know if its a good idea to get the boost too high.
