You could as an experiment knock something similar up out of a baked bean can. If it works then you have a template to make something more permanent out of aluminium.
Security system should not fail safe!
Security system should fail dangerous!
You can make these plates from virtually anything, the end of a bean can will be fine.
Take the EGR valve off for your template and whilst it's off give it a good clean up.
You could try disonnecting it first to se if that makes any difference. Pull the actuating hose off, or unplug the solenoid (under the battery - blue plug). Bear in mind that either blanking it, removing it, or disconnecting it is likely to give MIL and long term probably limp mode every now and again. But might help eliminate.
Also, the wastegate has nothing to do with the EGR.
Don't sound much different to what I remember, you need a calender for a 0 - 60 times lol.

Are the brakes also hard? I wonder if you have a vacuum leak so the turbo isnt going on boost if its the VNT type.
If it's a conventional fixed pitch turbine you may have a clogged cat or a leaking exhaust at the downpipes? Exhaust pressure is what spins the turbine up so if its not happening at low revs it has to be a gas-flow fault at the hot-wheel side - or an air leak at the intake side so boost is low. Look for split pipes especially underneath the pipe - on any hose that connects the turbo to the intake.
If it is a stuck-open wastegate then blanking it or jamming shut may result in overboost and head gasket failure or conrod bending. It needs to work to relieve excess pressure from the turbine when it reaches the stall point on boost. Excess pressure opens the wastegate to keep max boost limited and constant according to load.
Maybe the WG spring is broken, or its clogged with carbon, if its carbon it can be cleaned using mr muscle oven cleaner spray (sodium hydroxide) - needs left in it for about 2 hours then blown clean or taken for a run.
just found out it may be a VNT/VGT variable pitch turbo so you are looking at low vacuum, boost leak or sticking boost actuator to the vnt mechanism (on the side of the turbo).
