gauge or turbo or tmap

  1. Boost Gauge/Turbo/TMAP??

    Alfa 159, Brera & 946 Spider
    Hi guys, Quick question - I've got a 1.9jtdm and it's being an Alfa. Can someone have a look and tell me where their boost gauge sits at tickover? I'm not sure if the VNT vanes are stuck or the TMAP sensor is knackered, I get very little torque low down and then a wallop of power at about 2.5k...
