FX Help with tuning Wildcat down

I'm new to the WC, but not FX, as I have a Crown and Dream Tac, and have had Impacts etc. But, I have a question about the WC tune.

I want to tune it down to shoot 18gr pellets for a while, and am having trouble getting below 950 fps.
My current tune is
1st reg ~135 bar
2nd reg 80 bar
hammer 1 ( hammer screw is at 5.25mm and hammer weight is 11.4g)

Do I need to go to a lower hammer weight for pellets? My thinking was that 11.4g is the factory original hammer weight for 22 cal. So I'm not sure how to go a bit lower.

Is the micro adjuster screw backed down? I was around 900 fps with a 700mm at 130 bar for the impact and my shooting partners 500mm mav was very similar (wc in a chassis).

You have me wondering if you've got a 12-14 hammer weight in there too. Luckily hammer changes are fantastically simple on that platform.
