I believe what you heard is a "half" truth, part of a bit of advertising. The pods you are refering to do help the boat get on plane eaiser as opposed to a completely flat transom design. As you get on plane, the pods seem to act like an fixed trim tab keeping the stern from squatting and providine a bit of lift.
However, most use their tabs to correct a port or starboard list caused by uneven weight distribution in the boat or wind, adjusting the bow up or down to provide a better ride in snotty water or a following sea, etc. The "Pods" will do absolutely nothing to correct the trim in those conditions.
