Daewoo Cielo 150i chip/ EGR valves

Thoughts about EGR valves :

Disconnecting the EGR connection to the ECU may cause check engine 
code....maybe another way is as follows :
- If the EGR allows exhaust gas to enter the inlet by opening up 
passageways in the block (I can't see any obvious external connection 
on my 16V 2.0L GM) then why not physically remove the EGR from the 
block....fabricate a suitable blanking plate from a flat piece of 
metal to fit between the EGR and the block...then put the plate and 
EGR back on.
This would prevent exhuast gas getting into the inlet whilst also 
keeping the ECU happy because it can see the EGR electrical 
connection and the EGR thinks it is working normally.
- Also easy to remove at yearly emissions test time !
- Any effects likely on CAT ?

Anybody have any views/comments ?
