Oh what a shame my friend...as the valve train loosens up (valve lash increases), the valves do not open as much as they should and you loose power. I learned where the minimum valve lash spec really was (a few thousanths less than the published specs in the Bentley manual), and that's why the engine was so quiet, and was more powerful than your average ETA 6. It was like getting a slightly bigger cam (for free). You would have liked the 325e even more if I was around to make it sing. There's no valve lash adjustments from E36 cars forward, though. I prefer the older mechanical system, but those days are long gone.
The original owner of my "college BMW" also did a ECU upgrade. That's when you had to pull out the ECU and mail it off to get a physical change of your PROM chip (desoldering involved) from a tuner like Autothority.
