Sorry I havent had a chance to hook up the nitrous yet guys. Had to have a new rear end installed, now one of my Poston headers is leaking. I have an Nx gm efi kit, gonna run a 75 shot with c16 at the track, and alky/ 93 on the street. With a nitrous chip of course. I have a buddy here doing it in his car (el camino conversion) with good results. Soon I hope guys...Mark
