A few things you want to keep in mind while making a synth wobble.
1.) Filter movement effect is heightened the richer your synth sound is. Sounds are more rich with more oscs, sharper waveforms ( like saw and square ), and more detuning. Basically the more noise/harmonics you put into your sound, the richer the filter movement will sound. You can also add "grit" to a sound by adding a Tube D.
2.) Super huge dubstep basslines usually comprise of one or more synths. Or synth capable of rendering a lot of seperate oscs. if you wanna do a two pulv synth, keep one bassy and middle centered, and one more high end with it being spread to the left and right with either S.Detune or the Pan knobs on the Pulverisatuer.
3.) Experiment with not just 100% lowpass filter. Say put one of your synths on a lowpass, and one on a high pass, with seperately programmed automations. It's kind of a pain but yeah, it can work. Also try pulling the "mix" down with a Slope Plugin. Having partial filter effect can make it sound interesting and different.
