I have TR Customs down pipe with the external wastegate and I added a spring.

With the manual controller all the way shut, I was getting 24 pounds of boost so I added the blue spring that Tail says is 7.?? pounds and will open it some to get 27-28 pounds.

The valve did not want to go back on with the spring (s) in so I took them out and that did make getting them back in but I did it.

How do you go about changing the wastegate springs when you have done it ?
