The main advantage is ease of tuning, this lets you dial in the saw easier, but you won't really gain power. I know some like the coils from the 372xt that is limited to 13,300. The NE346 14,100 coil has a nice ignition curve and a stock 390 won't want to turn that many RPM anyway, that's what I recomend. And obviously the black non limited coils work well too, just don't rev the saw crazy without load. The 346 coil has a slightly different profile for the smaller flywheel, but it work perfectly fine. Stay away from the cheap AM coils.
