yeah i belive they are 19lb injectors but mine are yellow top, like i said its what i had to use but i can tell you it still runs rich Ive bumped my fuel pressure up to 50psi and it also raises with boost pressures,so with boost 65 psi on the injectors which may be to much but ive never hit detonation on it yet but im keeping an eye on it, as for my system i can tune everything on my ignition its has twin rev limiters,rpm windows,boost to retard deg i can set it from 0 deg to 14 deg retard per pound or boost and its messured through a 3BAR MAP sensor its a CD setup, hey randy77zt what MS were you running before you went to viper, 1 2 or 3? and how easy was it to setup the viper system cause ive heard alot of people curse MS installation
