Have you updated the tuner yet?
Are you hand calculating your fuel economy or going by the EVIC?
The EVIC is going to be inaccurate with the tuner on there.
The intake shouldn't affect your fuel economy either way unless you're pushing the skinny peddle more, to hear the new sounds. The EGR delete should actually increase your fuel economy. Did you disable/ remove the butterfly valve and actuator motor?
