Hi Gentlemen. I am a BMW girl and new to this forum. Just for the record, I do know a few things about cars and I look forward to great dialogue. I just bought my 4.4i with 19K miles and absolutely love it. I am also aware of some of the "issues" that come with this car but knew it would be worth the risk. I have read a few posts here regarding the jerking or acceleration delay on take off. I have experienced some of this and have had it remapped but it hasn't made a huge difference. Anyone have any ideas for me?
