i fitted the j valve the other day as i was told it would bring the boost on sooner, and help smooth things out a little, well i fitted it but the plug was the wrong way round so i put the valve horizontally and could just plug it in , i did however have to use a longer piece of pipe between the charge pipe and the bottom of the valve, but i have driven it but cant see any differences at all, have i fitted it wrong? or is the longer pipe affecting it?
