I've got a small block in my fj and have ran the holley pro-jection for a long time. I have always fought with it but it has worked semi well. After the last moab trip in May it has not worked at all. I pulled it off, thus forcing me to put something else on! Any suggestions...less the $500 would be ideal. I have several gm throttle body 350 with harness and computers if that helps.
