Now we know what is inside you can perform the mod to all your actuators and make them adjustable.
All you do is unscrew the air fitting and replace with an M5 x 40+mm fully threaded bolt, ideally a cap head not a hex but I didn't have one. The more you wind it in the greater the preload on the closing spring. Once set you just lock it off with the nut.
There's no need to cut another actuator apart, one was sacrificed for the greater good.
I managed to fit the bolt into mine earlier with everything in situ - tricky but I did it. I've got about 15mm of preload on the spring, you'll need a lot to open that wastegate!
