I installed Brisk 2MOR10S plugs gapped to 0.022". I do not remember experiencing any misfires with 0.018" on map one. However, trying 0.022" on map 2 gave me a cylinder 1 misfire with SES light and limp mode. I had to pull over and restart to drive again. I swapped Cyl.1 plug with Cyl.2 plug, but the misfire later occurred on Cyl.5 (sadly that log got lost in my other logs from auto-logging).
Sometimes, when driving with low pedal input, it will feel like I am accelerating and decelerating quickly as if I'm playing with the pedal ever so slightly. However, I am maintaining the same pedal position.
