On my 93 525 it doesn't have that great an impact at lower rpms (were I'd most like to have an increase) but at 4,000 it starts to make a very dramatic difference.
For 225. bucks, its cheap fun.
P.S. the install instructions I got did not mention the 4 Torx screws that need to be removed to open the brainbox. Buy a set of Torx drivers BEFORE you pull the ems.
