In the system description paper we demonstrated that PSR J1909-3744 was achieving timing residuals of just 66 ns over one year. 

 Marisa Geyer (SARAO) discovered that the energetic pulsar J0540-6919 emits giant pulses with energy sometimes concentrated across just about 100 MHz of bandwidth and published this in ui.adsabs.harvard.edu/abs/2021MNRAS.505.4468G/abstract - this is similar to what is observed in Fast Radio Bursts.
