    Help Wastegate

    Hello friends.
    Aid to know if I have the measurement of wastegate well.
    I have changed the chip of the ECU with Paul, but the pressure does not finish raising.
    As I said, to unseal wastegate in Barcelona to chiptuner and not if this good.
    I put the photo to know if this good.
    That opinion??.

    Greetings of Carlos

    First disconnect electrical plug from WGFV (N75).
    This means boost will be limited by wastegate spring.
    Check that maximum boost with standard spring is about 0.4-0.6 bar.

    If you aren't seeing ~1.4bar at full load in 4th and higher then you may have a boost leak.

    OR

    Sticky / Slow WGFV - when was it replaced ?

    OR

    Throttle cable not pulling round to WOT position ?

      I have proven disconnecting N 75 and the 0.5 bar pressure is of 0.6 bar , is correct?

      The fuel that I use is 98 without lead (that is worth 1.20 euro the liter).

      N 75 was put new 15 months ago, you think that the problem can be that?

      With respect to the photo, it seems to you correct 15 or 20 mm tight.
      Tomorrow hare the test that has requested me by MP
