    Transmission Tuning - E63S W213

    I have a E63S W213 which has 100 cell catted downpipes and am about to fit an Akrapovic exhaust. The car is lowered, has 21" wheels and produces on a 4 wheel drive hub dyno 720 AWDP and 940 NM Torque.

    I love the car and it goes much harder than my previous tuned C63S ED1 Coupe which ran larger turbo's. My biggest gripe is the transmission and the tune. The torque is limited in the 1st 3 gears and the transmission even in race mode does give the sort of positive gear change feeling that and speed that I would like.

    Is there such a thing as a Transmission tune for the W213 platform?

    I am also looking at the Weistec Stage 3 twin scroll turbo upgrade, they tell me there is no additional lag over stock my question is how can that be possible when the impeller size has been increased so dramatically from 48mm to 65mm ?

    This is my first post on these forums so please forgive if these questions have been answered elsewhere I cannot find them.

    Many thanks,

    probably not possible to have no additional lag

    the trans tunes don't seem to be wide enough use to get a good spread of responses
