dkp to 3 link learning curve/3 link tuning help

I’ve been getting used to my new board with 3 links for a bit, after being on dkp for almost 2000 miles. I have a few hundred on the new board, but I can’t seem to go faster than 40 without it feeling incredibly sketchy to do so. It feels like one twitch of the ankle will send me to my doom. I knew going from dkp to 3 links would have a learning curve to it, but I can’t seem to push over this 40mph ceiling. I weigh 130lbs without any gear, and about 160 with everything on (heavy ass tools and charger etc). I’ve got 87a krank in the front, with the rods in their loosest position, and 90a krank in the rear in the middle position, both front and back bushing nuts 1 full turn from hand tight. Am I doing anything wrong or do I just need a lot more time riding on these trucks? Full build is here, any and all tips appreciated
