    Update: Took off the mbc and installed the N75 correctly, now its boosting a lot more, 1,5-1,6 bar, sign of failing n75 and maybe why the mbc was installed... ?Have not tried to floor it properly but seems like I got rid of the fuel cut. Its holding boost better it seems

    Next will be to buy a new n75??

      Buy a new N75 and fit it. Doing so will rule that out before your do a boost leak test.
