Or could it be the wastegate keeping open? Seeing as its a new turbo and such we were checking the actuator and it was alright but it was on border line and further and it be open so yeh just seeing if anything can think of a reason...Before you say anything its going in for a custom tune but because of the V8's everyones booked out atm.

If so who sells them/ Link to comment Share on other sites More sharing options...

If so who sells them/The flap needs to have tension on it. With the rod pulled off it should be about half the hole shorter then the flap. You should have to pull the actuator about 3mm to make it fit on the flap. If it's not tight enough you will run less boost. Link to comment Share on other sites More sharing options...
