Depends on the fuel mods, altitude, turbo, intercooled/non-intercooled, etc. Only way to tell is to get it on a dyno. Might even be able to advance the timing without knock.

the adjustable cam gears for our cars are worthless.. wanna know more? IM me and I will tell you why..


secondly you could run a decent amount of boost, more then 10-12

the msd will retard timing based on the boost it sees if it is the boost sensitive ignition, over wise the cheaper box you can retard timing yourself up to like 8 degrees I think

i was running 10 with no problems, im not the only one who has done it, so 10 to be on the safe side, but im sure there is still a little room to turn it up

I've heard the MSD has problems with it failing.

well, im going to crank it up to 17-20 once i get my injectors and retard system, the only retard i have now is the driver. anyone know the difference between the dis and dis progamable. or should i go with crane. id like to have something to do the job right for the safety part but not spend too too much.
