Easiest way to get more fuel

I read the Advanced CIS Turbo Tuning thread with great interest and I didn't want to hijack it.

I have 964 3.3 turbo with a HF turbo that I run at 0.9 bar (EBC).
I estimate my hp to about 380.
It's a track car so it's being driven hard.

When logging my AFR using a Zeitronix unit, I'm running between 13.1 - 13.4 at full boost. Last time I checked it was 12.5, so it seems to be getting worse for some reason.

My engine is out so I have easy access to the WUR, the downside is that I can't check my system and control pressure.

What would be the easiest way to get more fuel and what should I aim at?
I don't want to go EFI or DWUR, at least not yet.

My initial plan was to make my WUR adjustable possibly moving it for easy adjustment (the WUR is hard to access on a 964 turbo) and adding a gauge for control pressure, is this the way to go?

After some reading I saw posts about increasing the system pressure to get more top end fuel, would that be valid in my case?

Thanks for your help, cheers!
