Have you driven it w/ a stick cabriolet? After-market exhaust with it stalling & turning back on?? I enjoy having the cab & slightly better sound w/ the tubi but on a nice day driving with the top down think it would drive me mad having the engine turn -off & back on...  

You could "save fuel" without paying for gimmicks you don't want or need but are getting screwed for in the price... If you're driving like how Porsche 911's are designed/meant to be driven & "saving fuel" you may as well buy a prius and save lots... There's plenty of opportunities to "save fuel", they've already designed the car to be more fuel efficient without gimmicks,,, saving 1mpg or less by stalling every time you stop is pretty ridiculous (is the word that keeps coming to mind)  on a 523HP Twin Turbo sports car with big spoilers, gapping radiator vents & 325 tires...

RE: 2. - It "worked"/works just fine without it

I'm sorry with this one Porsche had a brain fart...
