If you are adding boost and don't want to get into the whole standalone ignition thing then this is one of the answers that I found that will help you keep your motor from coming unglued.
I ended up going with a ford EDIS set up in my 924 ssc project so I don't need this anymore.
What this unit does is let you select (using a rheostat mounted on the dash) the amount the timing will be retarded per lb of boost. Up to 3 deg per lb meaning that if you are running 5lbs of boost you can retard the timing 15 deg. The best thing its the adjust-ability in the cab.
This unit is made by MSD for vortech it is the exact same as the MSD universal boost timing master p #5462

What you get from me is only what is shown in the photos. You will need to either get a matching pigtail for the plug or just cut and splice (hard wire) it in.
These list for $250-$300. I would like to get $125 including shipping to anywhere in the states. (or best offer)
As for payment I Prefer Paypal. If you are local I would also take cash. I am also willing to meet up with some one if you are in the metro Boston Ma area.
Questions offers post them up here. Pm me or email me at dsmith@radio.fm (paypal is the same as email address).
