Finally got it running last night. Had to flash a custom operating system on there to accomodate the 2 bar MAP. Ran like shit though, but good enough to get it home. Threw a P0200, open/short/problem with the injector circuit. I broke out the multimeter and injectors 6 and 8 were showing open circuit. This morning, injector 8 claimed to be good. Back off came the plenum and sure as shit 6 and 8 weren't fully seated. I also remembered last night that I hadn't attached the vacuum reference line to the FPR so I did that too while I was in there. Truck runs better than ever now so we can proceed with wideband installation followed by boost.
