Head to your dealership and get TSB #12-5-5 done. Then install a Mazdaspeed3 rear motor mount.

The TSB reflashes the PCM and will automatically raise the idle a hair when you release the brake, helping to get rid of the throttle lag. Also, the stiffer rear motor mount gives you a more direct throttle response instead of a 'rubber-band' effect.

FWIW, I also run 92-93 octane fuel.
