Do you mind Gav if I join you with my thanks to Simon.
It was really nice to meet him today, and even if my car still needs to be sorted out, it's much better now than it was before! The boost is much more smooth and very responsive.
And most of all its safe! On standard map it was running too lean.
Apparently there is a leak in my turbo inlet pipe (Simon noticed its a bit split at the turbo inlet side). The engine is unsteady on idle and has some hesitation at 3k rpm.
The inlet pipe defo needs to be replaced and then the map probably slightly adjusted.
Anyway Big Thanks to Simon, he's a true gent to deal with!
