haha Well in terms of fuel economy, my company car is diesel and I have to say that my heart still hurts when I see the average consumption on the Z4, especially when I am in the "mood" . Basically I would not want it to go any higher.

As for the RPi scoop, I have read around the forum and tests have shown that actually the scoop alone gives 5rwhp in NOT perfect conditions, which means that the bhp should go a bit higher up. Also having the power increase at speed is not a bad thing. Actually, when I think about it, this is exactly where I want the boost to be, after all you don't race at 40mph, you race at over 70mph
