Cats need to run hot to be effective, so the efi runs the system rich to keep the cats happy and hot, the tune resistor sees to that. If you are worried about smells put some of rice racer juice in the tank and will smell like cherries or what floats your boat. My v8 on carb diet no more smelly than my efi v8. And sounds better lol.
