I have 2004 b6 a4 1.8t k04. My issue is i have the stock n75, and ive been boosting to 27+ psi. Ive seen and when i bought the car the guy said it should only be boosting to 18 psi max. Ive thought that maybe my n75 could be bad?

 

Update, went ahead and bought a new n75 and installed, fixed the overboost issue!
