Hi, i have changed fron a replica wastegate to a genuine tial
wastegate but its now running stiffer
spring from the previous 0.6bar to a 1bar spring.. Car is running with pwn solenoid with boost by gear will i need a retune or which parameters will be affected? Thanks in advance

Sorry just to add, the new wastegate is the same 38mm as the previous one

You will probably need to re-enter the boost vs. duty cycle table to suit the needs of the new wastegate.

That was what i am think too.. Thanks for your time and input
