Vacuum

so I’m running a lsx 422 12:1 solid roller 276-294@0.50 .758-.722 lift 114 separation 112cl cam

ported ls7 Frankenstein heads Holley hi ram intake 102mm tb using Holley dominator Efi.

I’m seeing 90kpa at idle no vacuum leaks that I can find. Fairly stable idle at 13.8 afr My question is does this vacuum sound reasonable? It seems like it’s crazy low

What altitude/baro pressure? What does it read key on before running or if you stall it?

That is a fair bit of cam isn't it? Wouldn't expect it to pull much. Have you played with/confirmed cam timing?

Sea level. Reads 100kpa key on engine off

no I haven’t played with or confirmed cam timing
