If you had manual or SMG there was an additional mod

At the end if you will make some mods imho your 545i will keep up to the manual 335, even remapped .

Changing the ratio in the differential to have more acceleration, but on the steptronic many think it isn't doable .
How do you like your remap? Do you feel a big difference? Which company remapped it? Thanks.

Is it "doable" on an 08 550i Step Tranny? I've seen and read about it but only thought it was for manuals?
How much would this cost and does only Dinan doe this kind of work?
