Totally makes sense on overpressure while lifting when deep in the powerband. Certainly a problem in an autox or OT situation.

Troy had this same problem smallest 3 pc Holley pump with the dual Hemi Super Stock Holley 1850’s in his crosssram 472 Hemi with manual valve body. He added a regulator to solve his drivability issue. It wasn’t lifting in high throttle. It was just getting off the freeway and coming to a brisk stop.
This might be possible cause for issue in more situations than just autox and one track.
