Pull Timing Boost

The hei method does work but not well. Reason being it pulls all the timing all at once, so you get say 3psi with 10 degrees of retard, and 10 psi with 10 degrees of retard. It will work but there are better options. I use an MSD 6btm with the rotary dial to pull X degrees per pound of boost and it’s very simple. The next turbo build (I’m currently doing) is getting an MSD digital programmable 6AL-2 so a boost referenced curve can be built in a laptop.
