Welding tips are a couple of quid for like a pack of 4 ... but dawes devices are great .

That makes sense and I probably have one laying around here. I was just trying to hold on to keeping stock appearance and safety. If I keep the solenoid and put the manual controller directly in front of it that should still provide the same safety check (knock based) as before, and should minimize any spikes.

Can you install the dawes device (ball-spring MBC) in line with the factory boost solenoid? I am thinking this will retain the stock ability to pull boost if is senses knock. It would hold the line closed until the desired pressure is reached, and would then allow the stock solenoid to open the wastegate. Am I missing something here? Any reason NOT to do it this way? I am planning to set it at 12 psi or so since the fuel system is stock (as far as I know). I need it to be reliable and safe.

It would sense knock with or without it ..... a fades device just bleeds off until the the required BOOST pressure is reached ....

Right, but without the stock solenoid it can't open the wastegate at .5 bar. Am I thinking correctly here?

It will open the Wastegate at whatever you set the dawes device or bleed valve
