mikew 0 Report post Posted March 24, 2006 hi ive chipped many bmws 325,328,330,535,540,m3,m5 they workas long as u match the chip in your ecu correctly to the correct modifyd program, rule of thumb 10% gain so the more power you start with the better the gain Quote Share this post Link to post Share on other sites
