The Provent 200 is a 'must have' in my book.
I would also think about getting the intercooler cleaned out because after 70k it's got to have a lot of oil in it?
The EGR blank with a 6mm hole in it, as some use, seems a bit of a waste of time? Surely it's better to cure the fault that causes the low pressure code than have reduced carbon in the manifold?
Have a look at the small rubber hose that supplies the pressure to the MAP sensor, it's going to be in a different place when it comes back. If you can source a little one way check valve to fit that hose dia I'm sure it would fix the code.
Just fit a 'T' piece in that line and have the check valve coming off that fitting allowing air in but not out.
When it's under boost it will be closed but when it goes into negative pressure the valve would allow air into the line and stop the low reading that throws the code.
Either that or run the new hose from the 'T' piece to the upstream side of the EGR throttle valve as has been proven to fix the problem.
Something like this would be ideal!
It mustn't be fitted in the line, just fed in via a 'T' connector. Air in but not out.

I'm lucky, the 100kw 2.5 doesn't throw a code with the blanking plate fitted.
