Need some help. I have a 99 GMC Sierra with a 5.3L and a Whipple. When I am driving at PTO and my vacum pressure is at 10, I notice a slight whistle noise under the hood. Any ideas on what this could be? It only happens when the vacum is at 10. Thanks in advance, Kent.

Re: Need some help. I'm an idiot.....i take a bottle of water...wd-40 or most anything and spray around potential leak areas and usually the motor will change sound/rpms when you hit the leaking place.
