Have any of you modified your 528s? Our 08 is almost out of warranty and I was thinking of trying to put the X3 intake manifold and ecu programming in for 30 more HP. The car is my wifes and Im stuck driving it since I sold my 330. If anyone has any info on this please shoot me a PM or feel free to post here.
