as above really the car is really slow and struggles to rev above 3000 rpm, no turbo kick. Starts fine/ no smoke/ doesnt use oil turbo shaft has very little play and spins free. Put a boost gauge on it today (plumbed into the feed to the boost soleniod) and it only shows a vacumn when driving. Can anyone point me in the right direction - i suspect the wastegate flap is stuck open?? I'm more use to petrol turbo cars than diesel.
