So I am using 2 S9 SEs.

From bitmain, they show the other S9s operating on Low Power Mode at 14 TH/s at around 1300 Watts https://support.bitmain.com/hc/en-us/articles/360019738593-Difference-between-Low-Power-Mode-and-Low-Power-Enhanced-Mode

But as I mentioned, when i put mine on LPM, it only does about 3 TH/s. I'm just wondering if I have to wait 3-5 hours for it to 'optimise' has rate. Sorry these are some basic questions.

Have you flashed the unit with the latest firmware? I mean the latest firmware from Bitmain?
if not flash it first and try it again because 3TH/s is a huge drop from 14th/s you might also need to check and maybe it's overheating that is why you just got the 3TH/s.
Check the kernel logs why the hashrate drops a lot.
