There was a final hurdle to master, which has now been overcome.
My Amuse front bumper with its curved under-tray interfered with the lower boost pipes. Below photos show the issues on the passender (left) and driver side (right)
In order not to stress the fibre glass bumper, H-Dev opted to re-mould the under-tray (fibre glass) to give enough clearance for the pipes. The raised black sections need to be remoulded and lowered slightly. This should give an OEM-like professional look.
I think the result looks very good:
Road test is now done. All systems OK. Craig said the boost comes on very early, pulls very hard. Should have some dyno sheets later this week
