...Can my local dealer "tweak" the computer to show the correct speedo reading if I were to go to a larger tire/wheel set up?...
No tweaking is necessary, your stock 16" wheels probably have 205/55-16 tyres on them to give a nominal diameter of 632mm. An equivalent 17" diameter wheels and tyre combination is 225/45-17, having a nominal diameter of 634mm - less than 0.5% difference.

Just make sure that the wheels you choose have the right bolt pattern (5 x 120mm) and offset of 47mm or thereabouts.
