First of all, don't just blindly believe what's printed on the packaging.(posted 8517 days ago)The developer I've come across that gives the most speed increase is Microphen, and that's only 2/3 stop. Many others (Acufine, T-Max, Xtol etc) only give a 1/3 stop boost.
Developer manufacturers may obtain a "speed" increase by recommending development that results in higher-than-normal contrast; this is otherwise known as pushing and doesn't significantly increase shadow density. The effect is usually the opposite; blank, empty shadows and high contrast.
Developer manufacturers may obtain a "speed" increase by simply assuming that a 2/3 stop or more underexposure is acceptable and you can simply print on a higher-contrast paper. This is usually known as "rescuing an underexposed neg."
At any rate, to specifically answer your question, set the meter at EI 200.
