99 tahoe shutter/roar

I have a "roaring noise when I back off the accelorator partially. Did that happen to you?

Also the shutterring happens when going uphill under a load.

I was told to ck the vacume booster on master cylinder since it seems that the roar is coming from behind the left vent/tach area. And that the shutter may be from the brakes pulsating (ie. abs)
