careful about changing intake if it bothers airflow I changed mine and the air sensor wouldn't let engine pickup rpms without computor mods

Most always that's if you change to an LBZ intake / change the filter side of the MAF sensor.

Is there anything wrong with blocking the egr off?

Not a thing. Most enthusiast do.
