No problems before. Then I tighten 4 turns. problems. Now its loosened 2 turns, so its back to being 2 turns tighter than stock. Think i should return to 0 turns and see if problem persists? I find it odd that a highly recommended mod on my WG actuator arm could cause such issues, but its definitely possible I suppose. I just didnt think I could really overboost with only 2 turns on the arm.
