I spoke with one of the techs at my dealer who has gone to E90 school. He said no more replaceable chips, but reprogramming is possible, commenting that someone ineveitably will figure out how to reprogram a 325 into a 330. (His bet was Dinan.) Suggested that if you want more power the place to start is with the exhaust+muffler system, then the intake manifold.
