Default Slight bucking/surging at a VERY small amount of throttle (20 inHG), any ideas?

When I barely press the gas, just to keep speed, I am getting a really small buck, on and off. Could it be my divertor valves? They are somewhat old. No codes or anything. Car pulls pretty strong but it has a tendency to break in and out at WOT.

Car holds boost fine and sometimes acts perfectly normal. Any ideas are appreciated. Thanks.

Have you checked codes and done a pressure test?
