I answered my own question by going and looking at some pictures.
drdehave, the speed that you picked up would not be due to the trim adjustment. With an elevator trim tab the adjustment you made would have allowed greater deflection of the trim tab to position the elevator to maintain level flight. The greater deflection of the tab would lead to more drag, not less. To reduce drag an adjustment to the airframe to decrease the trim tab angle would need to be made, something like changing the angle of the horizontal stabilizer. Maybe the increase in speed was due to some other factor, like cooler weather or a more aft CG.
