knock during highway cruising then popping under boost

[vacuum 6]

Wanted to share since this is a PITA for us all.

Started getting knock while cruising on the freeway. It got worse when engine temps increased. After a few weeks the engine started popped @ 5# of boost.

Check fuel, alky, vacuum lines and added race gas, nope still there.

Swapped out the coil pack bingo all issue went away. Hope this helps someone.
