If it is for sure an original actuator it should be 11psi for 1g, VR4, and evo 1-3 actuators according to extreme psi and the OEM wastegate they used to sell.Is there a difference in how much pressure it takes to open waste gate actuator on different Mits turbos? I need one for 14b so need to know if all the bigger ones need the same pressure to move actuator and will work.
