Kiwi1989 New Member 13 Member For: 5y 8m 22d Posted 20/04/19 09:25 AM Share Posted 20/04/19 09:25 AM Hello there. I need some help. I have a ba xr6 turbo with some mods done. I have the turbosmart wastegate. Now my mechanic has told me that my car is overboosting. The wastegate is starting to open when im at 20psi. Which he tells me this can cause major problems. Why could this be and how can it be fixed? Link to comment Share on other sites More sharing options...

Kiwi1989 New Member 13 Member For: 5y 8m 22d Posted 20/04/19 09:48 AM Author Share Posted 20/04/19 09:48 AM Pretty sure its internal. Sits off the turbo. Can you adjust the boost levels through the wastegate? And how is it fixed fo get it back under control? Link to comment Share on other sites More sharing options...

If that doesn't drop it enough change the spring to a lower rated one.Chances are it's a 12psi unit which has a 5 and 7 psi spring in it. Link to comment Share on other sites More sharing options...
