Is anyone currently running the GM VRFPR? I wanted to change my Jet adjustable FPR as I wasn't sure it was working right so I bought the GM VR one. I've since read on other forums that it's no good for an 'only slightly modified' 350. So has anyone got/had one? Did it work? Also, the vaccum tube points straight into the venturi, surely it doesn't get it signal from the pressure drop in the venturi does it? Any feed back would be appreciated. Oh, and if they are no good....can anyone recommend a good TBI FPR?
