But, that's because I've mastered the modification of the engine components on the www.454ss.com . My conclusion is that BMW's are generally driven by people who have never lifted a torque wrench. Mostly, a toyota camry owner with a few bucks more to spend.

I'm just writing because I thought at first that there might be have bben some knowledgeable folks here who can provide input concerning injector size, fuel pump capacity, and computer rpm limits, but, evidently I am mistaken.... BUT, the Americans really are a bunch of candied apples; my europals are wise.

Judging from the biquering witnessed concerning an alleged dyno result, it is clear that few US citizen BMW owners have any chance of achieving appreciable performance modifications over the stock configuration, without being hoodwinked by their "mechanics".

If this offends you, GOOD !!! :) enjoy it. :):):)
If not, that's even better. There may even be hope for you yet. Till then, enjoy the view of my rear bumper.
