Ford GT and Dodge Viper SE controller

People have reported that the new SE's are faster and have longer run times. I was just wondering:

-If you charge your old SE with the new controller, do you also get the longer run times?

-A peak charged car will run faster than a partially charged car. If the new controller does give the old SE's longer run times, what is the speed comparison against the new SE's?


On a side note: As a mechanical engineer, I must say that Radioshack either has the worst quality control engineers in the country or they are knowingly employing this technique to try and force sales. Either way they're pathetic.
