7 Series - E65 / E66 (2002 - 2008)
I have been taking my 7 in since may of this year for bucking sensation from 40mph to 30 mph. 1st I waited on new update for trans(did not work) then the super program directly from BMW(did not work) then megatronics(did not work) there are no doubts that these thing has made some improvements...
