OK im more confuesd now but thts easy to do LOL so is a 100 psi fuel presure guage the one to use then ? and mabey i can get some of tht sweet braided line from you it looks like i tap it into the manifold like a pyro ? or would somewhere on the turbo be better ? and a little lost on wh you where swicing pins and what not was tht so you could set up logging with efi or something ? would a 100 psi boost guage work ? instead of the fuel presure guage ? Thank you
