That might really be all I need. It doesn't need to be fast it would just be nice to get out of the way a little bit better and not wind out to 5-6k every 3 seconds.

Of course, coming from a drag-racing and vintage muscle car background, the term "stage one" brings two things to mind: 1) the Buick GSX 455 "Stage One"... "For 1971, Buick added the brand new*455 cu*in engine into its restyled GS. The Stage 1 package had an even hotter cam, bigger valves in special high-compression heads, a distributor with a different timing curve and a modified Rochester carburetor." It was a beast of an engine in a great looking car, that I admired and actually trained working on in '72, at the GM Training school (under Buick auspices), and raced against several times in my highly-modified '66 Chevelle. I had more horses, but the Buick had more style!
and 2) a Nitrous Oxide "Stage 1" injection kit. Which usually means a single stage of Nitrous squirted into the carburetor or into the manifold runners (in 50 to 150 HP-adding blasts). Some racers used several "stages" of injected Nitrous, but many went too far and blew their engines. My personal experience with Nitrous was with a 50-hp "top shot" kit, that I configured to squirt down from my air cleaner into the carburetor secondaries at wide-open throttle. I used it for a very short time on my early 327-400 HP street-strip engine, and it certainly would up performance instantly. I loved the increased performance, so much, that I went to a big-block 427 for the next racing season (sans Nitrous). If I had the money, I might try a 50- hp Nitrous kit on the M54, but my budget precludes buying spare engines.
Also,
motordavid stated that he had "opened the moon roof maybe a half dozen times; don't care about it but the point is the less a moon or panorama roof is opened/closed the less likely it is to every leak, imo"
which I agree with, wholeheartedly. In fact, I disabled and sealed mine (using clear Paint Protection Film), so I'd never have to worry about sunroof leaks again. The clear film isn't noticeable, and lasts for years, even exposed 24-7-365 to Texas weather, but I check it every time I go out to the X5, just in case.
