"Blackout07-13-2007, 12:34 PMi cant really compare taking both on the track but ive taken my 318 on the track and all it has is a chip and it was extremly nimble and quick it kept up with quite a few cars in the corners granted it does lack power for the straight. something you should look into is the DASC that they are making for it http://grassrootsmotorsports.com/images/bmw_pdfs/june06_318is.pdf" .
