I just don't have good knowledge of what maximum wattage would be on the 2 cell powered version with your build. But just going off the fact that 167 is 2/3rd of 250 then 2/3rd's of 175 watts is around 115, I'm just not sure if this is how it would work out or not.
Well then my earlier posts were made thinking it was a 3S lipo pack. Connection from batteries to battery contacts need to be considered as a possible problem perhaps, I'm not familiar with what they used there.
I see no reason that you shouldn't be able to achieve your settings providing the board is receiving correct power battery wise. What battery/type powers your mod. If I have this figured right (looking at the data sheet/output power) you should be able to hit around 175 watts with that build.
I bought some 430 from CW, works just fine for me. I made some Claptons with it, 2 strands of 25 gauge CW 430 wrapped with 34 gauge Kanthal dual coil build in a Velosity
My SMY SDNA75 lives an even a tougher life than Chunky's although in a different way, I gave mine to my wife and it still works. She takes chain vaping to a whole other level. On the serious side I noticed no difference between 75/200 as I only vape at 45/35 watts.
I used this one in my Vapecige VTbox200, it appears to be the same case. The power wires needed to be shortened and I had to change the plug to a "T" plug. Later Vapecige boxes use a XT-60 plug. https://hobbyking.com/en_us/turnigy-nano-tech-1300mah-3s-25-50c-lipo-pack.html
