Ok. I understand. So did you set a timing curve, or lock the timing at a specific degree? I don't have the handheld in front of me to tell you the exact term they used
I run 18 idle/initial, then at 1100rpm I'm at ~26, at 3k I'm all-in at 32 and at 6k still 32. All the 45kPa values are the same - 45 degrees.
Runs great. I've found that proper timing, well-sealed exhaust (no header leaks, no collector leaks), are very important for the system to run well. I also run the lower revs a little richer (13.5-13.6 AFR versus 14-15 at high vac and higher revs) to avoid stumbles.
