woops, my bad.....
I can never get to "7"..... I drive the lowly E55 which only has 5 speeds. HA!
These type of threads cause me to wonder if the transmission software can be "updated" to give the new throttle-blipping feature to an older car? Tuners have hacked the engine management software, so I'm sure it's possible to hack the transmission controller, ESP functions, or whatever.... somebody with the knowledge and resources would just need to invest the time to do it.

Exhaust note changes after engine braking
So I have been using engine braking mostly for the sound, and i noticed the other day that the exhaust note, once the car has been completely slowed to a stop, is much more boomy as i slowly take off again, but only until i start to apply moderate throttle. I understand engines and mechanics, but not sure what would cause this. It's almost like there's a bypass kicking in when I engine brake, and it's staying open until i give it a relative amount of gas to accelerate again. The exact steps followed (and repeated a few times) were to blip throttle while downshifting through 4th gear, all the way to 1st. Then i take off in 1st very slowly and the exhaust note is very boomy/resonant, and if i give it a little more gas, the resonance quiets back down and sounds normal again. It's very pronounced.
Also, I talked to my MB dealer about engine braking to avoid brake dust, and although not an AMG Performance Center, their opinion was it was kindof pointless. They said the car is constantly braking in corners and other times, even though my 07 model doesn't have SBC, and straight line engine braking would only be a fraction of the braking action that actually happens with the car. Not sure how true this is and they sure didn't give specifics but it's something new I didn't know about my car.

Haters crazy
Its when you miss the blip that could cause problems. I use to do it all the time, than when my sc clutch cracked, I stopped doing it all the time. Im sure its ALOT more harsh on the engine/tranny/diff.

You guys know that you can use the shifter miss gears when down shifting to the lowest gear possible so if your cruising at 80mph and want to kick down two gears to really lay the smack down on something using the tiptronic style and holding it in the down shift position the thing will drop to the lower gear possible so straight from 5th to 2nd if possible.
The thing really tears *** when you hit the throttle at the same time as doing that....
I assume this could also be used to engine brake the car but have never tried it. Could be wrong.
I would be more concerned about the condition of my flex discs on the driveshaft if doing this constantly. Failure of that front one could get very messy.

Every time I downshift from5 or 6 in S+ mode I get the sweetest double clutch, which, I have been told, can be heard from a good distance! It makes me forget the cost to get it.
