### ⭐⭐⭐ 







  
  
    No consistent regulation of boost
  

*by A***N on Reviewed in the United States on June 3, 2022*

When first installed this 12psi spring only held 10. As time when on it held less and fluctuated even between gears. Not a very solid wastegate spring

### ⭐⭐⭐⭐⭐

### ⭐⭐⭐⭐⭐ 







  
  
    Did it's job
  

*by A***R on Reviewed in the United States on October 2, 2019*

Did exacally what I needed it to and stopped my wastegate flutter under boost beyond my old springs capability.  The thing was pretty tough to put in because it has so much tension.
