Is the pad saver gunking up the body octave vent? Use a pipe cleaner from the outside or a bent paper clip from the inside to be sure the vent isn't clogged. Clogged (partially clogged) octave vents can do weird things to your horn. I've never used the stuff, so I don't know what it does to the pads. If it makes them swell at all, you might have leaks developing if one swollen pad is lifting the action on another. The best way to look for leaks is with a rope light jammed up your horn's kazoo. Undo the springs and see if gravity (only) will close the pads thoroughly (holding the horn horizontally). In a darkened room, very little, if any, light should be escaping between the pad and tonehole. You shouldn't have to mash the keys down to play. This is the most thorough way I know of to take care of pad leaks.
