That's what I said in the next couple of sentences. I didn't write the bit in the quotation marks.
The Egr valve has a hefty spring in it. When I removed mine I left it to soak overnight in some Gunk and then removed the gunge with a toothbrush.
It cleaned up as new.
I thought I'd check to see if was operating properly and hadn't siezed. so I inserted a piece of copper pipe in the exhaust gas inlet of the Egr and pressed. Didn't move a millimetre!! found that to move it required me to put most of my wieght on to it before it would budge, but wasn't sticking at all.
God knows how much vac. you need to open it?
The Intake mod lets the engine breathe better, but if you dont put in the egr bypass the air is hitting an equal reduction in size later, making the intake mod on its own limited in it's effectiveness, if not pointless IMHO.
