well go figure the trucks tuned with efi live with a 5way switch. followed the wires and there hooked into a harness up front. so we reconnected the switch and it seems to change somethign not exactly shure what yet, but the idle changes and one of the tunes dumps alot more fuel. got a boost guage from twigbert now just waiting for my 12' boost line to show up at work tomarow i think i'll be needing a pillar pod soon tho
