After doing work on the top of my 3.8L V6 (all this), I'm attempting to tune my motor. I checked timing & it was at about 10 degrees; factory is 15 degrees, and I now have it at about that, probably within a degree (& I'll fine tune it if I need to).
I checked vacuum next, at the brake booster line (without the check valve). It's a little low, as seen below & as shown in this video: Vacuum
The gauge suggests late timing. Should I go back & adjust timing further using vacuum as an indicator, or look elsewhere first?
