Here is a video of the lope/cackle.
I guess me clipping the video doesn't really show it. But it almost sounds like it's catching itself in person.
I'm all for replacing the HPOP if I need it, I just wish I knew that before I swapped everything over if that is what is wrong with it.
And per my comment last night, It was no where near a major lope, it was just a slight difference in sound if I cut out of the throttle fast.
