Ok I am wondering if anyone here has experienced this. My wife was complaining that she thinks here 4.4 sport had more power than her new 07 4.8 sport. I assured her that she has 60 more HP and I feel it is just as fast or faster and asked her why. She said when she needs to mash the gas and make a pass the car hesitates for 2 sec and then starts going fast. I then though that she was not pushing the peddel to the floor . So I was with her and told her to show me and sure enought. Since I have alot of trans and motor experience I did a few tests which I used to do to check trans. I can mash the gas, force the engine to spin up and have the trans lag for 2 seconds and hesitate really bad. This shows up in sport mode and regular mode. I tell you it is very noticable. I am just wondering is anyone else has experienced this and if the have was it fixed by BMW?

Thanks
