    Hi guys bit of advice/help needed got a vento 1.9tdi AHU engine code, my question is about boost what is standard boost pressure? Mine is boosting up to 18psi first and second, then in third it hits 18psi then drops to 13psi very suddenly, so what's going off guessing something is not right? The only mod so far is decat. Only just fitted boost gauge today so only just seeing the issue if there is one, I would like to remove the n75 valve and fit a manual boost controller, and bleed valve in between ecu and boost pressure to fool ecu to make its still boosting but lower down is it possible?

    Thanks in advance

    Does the car drive okay? If so, leave it alone and stop having grand plans to blow your engine up.
