DMS chip for e46 M3
Discussion
They will remap your current ECU, not put in a new 'chip'
If you value your engine personally i wouldnt bother. A more aggressive driving style, coupled with a higher rev limiter can mean oil lubrication issues and engine failure as a possible result. The engine is stressed enough at those kind of revolutions. For the sake of .5 seconds for a 0-100mph or whatever, not worth it IMO.
Some people note noticeable results though.
