I have a t25 that runs 8psi with the stock actuator. I want to lower it to 6psi for my stock d16. Can i cut the actuator arm and creat thread on each end and put a long nut in between them like the adjustable regulators? ie make the actuator arm longer

 

you can also put spacers (washers) on the wastegate actuator mounting, to extend it out, to get the same result.

I have seen actuators with the adjustable arm, who would sell them and are actuators interchangable?

 

nobody sells adjustable actuators for dsms,

and no they are not interchangable.. they all have differnt mounting brackets. If you can rig one up, it will work however.
