Proper EGR delete

I'm looking to delete EGR from my 2007 Mazda CX-7. However I'm not satisfied with just physically deleting the EGR and masking the CEL code, I want a real delete with proper ECU re-tune that restores the MPGs and deals with lean mixtures. Does anyone have a map for this or know how to do it?
Thanks!

Deleting the EGR will simply affect the fuel economy just because the chemistry going on inside the engine will be different.
To counteract this you can increase the closed loop timing but it may not work as well as if you had the EGR.

The only benefit of EGR delete is a cleaner intake. EGR generally increases low load cruising fuel economy.
