For anyone thats interested i have a 2006 320d M Sport (163 bhp), standard 0-60 figures are 8.3 sec
Mine has been remaped to 204bhp. Yesterday me and a mate on a private road used a app on his i phone to do some 0-60 times, i had a few runs and all of them under 7 sec and the best was 6.5 sec.
Dont know how accurate these are but we did try 2 different kind off apps.
Here's a little guide from Parkers....
325d (194bhp) 7.2 sec
330d (227bhp) 6.5 sec
325i (214bhp) 6.5 sec
