Ok ok, I'll believe you guys about the eta. But I still have a hard time accepting the fact that a chip would do much at all for any other otherwise stock naturally aspirated car. Wouldn't a company as reputable as BMW have tuned their engines and tweaked their programs to "perfection" from the factory already? h:

Oh, and the dyno day sounds cool but I don't really have any desire to put my stock d series on there. I can imagine that there should be some awesome cars and neat setups though!
