I'm havin problems with mine fellas, even setting it as far out as possible(keeping tension on the spring), I'm running rediculous boost(my FCD keeps cutting fuel off at about 14/16psi) but I only want to run 12! Any suggestions on what to check? It's connected correctly, thanks.
Edit: Oh yeah I have a 1990 Celica GT4 but I don't think it really makes a difference.
