    Boost leak, Weak Actuator or boost gauge?

    Hi All,

    I have a bit of a problem with my boost at the moment. When i floor it in 2nd or 3rd i reach about 5000rpm and the boost starts to drop dramatically until about 11 psi up to 6500rpm

    Now when i hit boost around 2500 it goes up to 20 then almost immediately drops to 17-18psi then holds and drops as above at around 5000rpm.

    So is it just my pathetic noob turbo (k03), a boost leak of some sort, my actuator (r-tech said it was weak when i got it remapped last year) or just a dodgey boost gauge.

    What you reckon peeps? I plan on getting it scanned this weekend if i get time. (which blocks do i measure for boost btw? (can u do it on VCDS lite))

    Cheers!

    they can loose their performance and ability to hold boost at high revs with age.. and leaks will murder their flow/pressure ability.. Also well worth checking it for leaks.. smoke test reveals all sorts if you have somewhere local who have this kit
