For Boost Retard, I have a MSD 'Boost Timing Master' (in the box on the shelf). It's just a timing retard box, with a control knob that lets you select how many degrees to retard per PSI of boost It's the cheapest I have found amongst the name brands.
I got mine from that auction site.
The PN I'm coming up with, off the MSD website, that matches the specs of my BTM (from memory, who am I again??) is the PN 5462.
This one ends in 2 1/2 hrs, less than I paid for mine (no idea on the seller though). (#220237660856 if the link doesn't work)
