But there is two sides of egr, some people has clogged egr's, when this happens, the fuel conumption increases more than if you dont have any agr, and ther's a(big in some cases) performance loss, it's not noticeable because its progressive whit the years, only noticeable when you clean the egr.

The problem removing the EGR is due to the stock ECM flashing error codes and running on a different injection map like the engine had a malfunction. I've already seen some EGR disabling plates mounted between the EGT sensor and the EGR valve which actually led to increase the fuel-efficiency, and even the turbo had more boost from lower RPMs.
