Pull Timing Boost

I have that same (MSD BTM) set up and while it works, it's not optimum. The P.I. distributor is extremely simple and fast and pulls timing when, where and how much you program it for. Not all at once. Apparently this new 6AL Utra Plus does the same for a little less $
The 6btm was perfect for my situation, it’s in a boat and fuel efficiency is not of primary concern. On a street car when you’re not in boost it’s nice to keep all the timing in it for cruising and get the mileage back. It’s hard to do that in a distributor and a mechanical type retard system. The only real way to get there is by creating a 3d map in software and letting the box do the work.
