Another photo. It's so damn tough to illustrate that bump I mention. Hoping this photo shows it. It's there but understated .. you'd almost have to see it in person.
Incidentally there is another guy I just saw posting in the 5.7 HEMI performance area that has a thread going. He seems dismayed with the Air Grabber, but his issue seems similar to mine. He put flour on the upper portion of the AG seal and closed the hood. Clearly you can see that much of the AG isn't contacting the hood liner, particularly where the hood rises and leaves a negative void below.
I've asked him to try loosening the upper connector (AG tube to silicone tube) and after raising the tray, close the hood while loose, and then immediately tighten the connector again.
I'm going to try this as well when I have the first chance.
