Tighten the inner nut up and make sure you use a wrench on both nuts to keep the rod from turning. If you search EFR waste gate actuator preload, you'll find a few good reads on adjusting it.
I run the high boost actuator as well and run 4mm of preload. My WR3 came with the 179284 high boost actuator and just recently I had lazy boost response and was maxing out at 24psi where I typically run 27psi. I found a small boost leak that I thought was the problem but didn't fix it and tried everything I could think of before finally adjusting the preload. Not only did it fix my problem but I noticed a much quicker spool up and had to readjust my waste gate duty cycle down quite a bit. I had run it for 9 months with less than adequate preload and the difference it made by adjusting it was substantial.
Not saying this is your problem the picture of your log doesn't look good but it's worth checking.
