so I took my wastegate off and found a tear in the diaphragm. ordering a new one hopefully that'll solve any recent issue's.
update: took it off again and put pressure on the diaphragm not leaking. I put some silicone on the little slit just to see what I get. I recently noticed a slight flutter with the wastegate an that the body of it would spin. so when i had it off noticed the nut under the diaphragm loosened the set screw tightened the big nut and now the body of the gate is actually locked in place. seem's like it just loosened up with use.
