Make sure your tires are rated for these speeds.

You'll need to find out what is limiting top speed: the ECU or the throttle body. Once that is determined, you need to either replace it, remove it, or modify it.

You could look at http://hypertech.com/, though I'm not sure if it works for your car (when I searched for a 2011 Mazda 3, the 2.5L engine was not one of their options).
