you probably won't notice much. That engine doesn't gain much from just software. Especially on such a large car. I'm afraid the only way to get reasonable power on the big E39 is either displacement or forced induction.

At least he'll get some better response and torque off the line. May also make her more touchy on the throttle though. Is $500 or so worth it to you?
