This is without a chip, stock 15" basketweaves, stock air filter and dino juice (no synthetic). Bigger wheels will reduce your acceleration (more mass to accelerate - think of a skater with arms out and arms in). Just have not felt the need (nor had the time) to do much modding as I did with the e28. Probably the most stock car I have (other than the 02 C240).
Sounds like you may be getting some serious transmission slipppage or losses in the torque converter. The 540i auto comes with a higher diff (this is good for acceleration). Remember though, that the car is geared towards 150+ top end and not for acceleration (although I have no real complaints)
The reason I asked about 0-60 times, is that mid 6's is not to bad (downright respectable considering the weight of the car). IIRC the new M3's have a 0-60 of mid 5s and that with a much lighter car. Just wanted to make sure you have realistic expectations.
Hope this helps,
0-60 times I am not sure because I am not going to clock myself. But since you have a 540 also, let me ask you this... Mine is a '95 540IA with 63k miles on it. Even in S4 mode it seems sluggish off the line. I turn off the traction control but I still can't get the rear tires to squeal. Is this normal? from 500 to 2500 rpms the car doesn't have much go. I had the engine block checked too and it has been replaced. I am rambling, but a great example is that my wife was with a freind in a mini-van next me me at a stop light. Just for fun we raced. I kid you not, for the first 50 or so feet, that mini-van was a good distance in front of me until I got the rpm's up and then I dusted her. That still doesn't seem right.
