I would do. You need to make sure the LDA's working properly, if it needs too much boost pressure to force the pin down, it may not be reaching max fuelling.
I know on my 9mm pump the LDA made a huge difference and gave it more of a "kick in the back" difference between boost/off boost when I added preload. Could be what you're experiencing but with too much preload and a coilbound spring reducing travel.
What's the pump history? Who fiddled with the LDA?
