Peter, I was interested to read that in sport mode your Merc`s gearbox seems programmed to use engine over run on throttle off down shifts, causing a fruity note exhaust note, which is very much a part of my sports car ideals and the old +8 supplies that in spades...
My 991 however does not.. I do have push button operated baffles to provide a tad louder exhaust note and Porsche kindly provide a sound symposer to pipe induction roar into the cabin too.. However it would seem even in sport mode if dropping a gear, the programming causes the car to accelerate, no doubt expecting that throttle up will be the next command.. Which does not ideally suit my usual style of driving, and demanding more use of the very competent braking system.
My guess is that the programming is set to match highest urban fuel mileage or some such as may be required by legislation... Not quite my ideal but I will just have to suffer it for now...
