You may well be right about the pressure equalizing but I wasn't talking about constantly increasing pressure. Even if it equalizes, it will do so at some pressure level... What I am getting at is the constant pressure, combined with heat stress over an extended time.. With
most of the factory flashes, the EGR valve is open to some extent while doing anything other than idle or WOT. When the valve is open, there would be minimal pressure since it has an escape point to move the gases through it. Keeping that valve closed constantly will keep a certain pressure on it all the time.. At least, that was my theory, which may be completely wrong........
