Default Vacuum pump - 09-14-2019, 12:49 PM

07 335xi. I'm only getting 21in of vacuum from my vacuum pump. Is that too low? I've read it should be 28-29in.

I'm underboosting seaeching for the cause. There is no leak. It holds vacuum perfectly.

Judging from your username and low vacuum, I'd say it's all due to the altitude.
