I've got a similar setup but with the older Evo MkII fuselage system.
What sail sizes are you using and what wind angles are you sailing?
The 109 fuselages are really only for upwind/downwind racing. I use it with a 9.0 sail and 0deg or +0.5deg shim. The SLX wings are much more powerful than the previous SLR wings and I've had to reduce my shim angles for equivalent sizes.
Do you have shims for the UCS fuselage? I think they're an optional extra now but sounds like you might need to try a negative shim.
