YES!!! I had one go bad on my Black Z06 last year, about an hour to replace.
Figure 75 for a used one, pull the brake master cyl. and the 4 nuts inside the firewall.
Done.
BEFORE PULLING THE BOOSTER, pull the hose off and put your thumb on it to create a seal while the car is running to eliminate the possibility of the hose being bad.

Run the engine for a few minutes. Shut it off.
See if you hear the same noise at the booster as soon as the engine is OFF.
Wait 10-15 minutes and then pop out the vacuum line fitting on the booster! There should be a release of vacuum from inside the booster.
If you pop out the vacuum line fitting on the booster, it should release the vacuum. If it doesnt have any vacuum, the booster is bad.
