I have a b16a 2nd gen and i did compression test. Results were 150 psi on all four cylinders

Is this normal because i searched online and everybody got around 200 psi on their b16

Im planning to boost it thats why i need to know if i should go ahead and boost.
Btw my vacuum is 20in hg while idling which they say is normal. Doesnt low compression test result affect vacuum thus resulting in low vacuum?
Thanks
