There's sulfur in fuel additives; your engine isn't burning it completely and your catalytic converter is storing it and then releasing it as hydrogen sulfide when you add load to the engine and force more air through.

Try switching petrol stations, or fuel grades; then try a thorough tune-up: replace the spark plugs, plug wires, fuel and air filters, and oxygen sensor, and clean the fuel injectors.

If that doesn't do it, maybe time to replace your catalytic converter.

Smell off eggs usually a sign the catalytic convertors on its way out.
