Wastegate spring or Boost controler

When I measured mine with stock cams it was 13 inches of Hg.
Low compression engines make low vacuum compared to high compression engines.
When I was running .9 bar on my stock engine my boost control pressure was at the factory setting and my afr was about 12.5/1 at 6000 rpm. With cams I'm .2 bar higher on control pressure and still at 12.5/1 at 6000 rpm.

Thank you for your input
What gear are doing you testing ? As you know the lower the control pressure the richer.
I'm sure when I can find a safe place to do 3rd gear pull to 6000 rpm she should be in the low 12's hopefully

Third gear yields the most time at load so that's what I use. If your enrichment isn't quite perfect, you will see it in third.
Yeah, lower is richer. Thanks for that reminder. I ended up being .2 bar lower than stock.
