Will I get more Power and lower fuel consumption?

Is it risk for the EGR valve will stuck open?

No.

EGR is used to lower combustion temperatures by selectively diluting the fuel/air charge. It is fairly benign, and does not operate under full throttle conditions so you'll never really know when it is operating. Because it does affect part-throttle combustion, disconnectoing it - or a stuck/sticky valve - will usually give you a part throttle or off-idle ignition ping - sometimes constant, sometimes only three or four pings.

Quite the opposite. You'll get higher fuel consumption.
