Unplugging EGR Valve

I read on another link here ,that just unplugging the EGR will do the same thing as an EGR delete as the valve will stay closed , keeping exhaust gasses out of the cooler ? is this correct ? I plan on doing the delete kit soon , but will this also work for the time being ?

Unplugging the valve is not the same as a delete or blocking both ends of the EGR cooler. It will only prevent hot exhaust gasses from entering the intake manifold, you still will be allowing hot gasses to enter the EGR cooler. If you decide to unplug the EGR valve, just be warned that with some year trucks with certain stadegies when you unplug the EGR valve even with the delete you may experience side effects. Side effects could be that the VGT will not cycle at idle, clutch fan will not get up to full RPM speed, and you may throw a CEL.

The CEL and VGT cycling is something you can notice without a good scan tool, but the clutch fan RPM you will not be able to determine unless you run test with a good scan tool that can read and graph the RPM out put of the fan.

Unplugging the egr will keep the intake boost in the intake system. Pluging the vent to the egr cooler from the up-pipe, keeping the exhaust pressure in the exhaust system.

Just unplugging the egr, the exhaust will still put pressure in the egr system.
