OK Folks, short of going down the supercharger route, (but if I can find one, I will have it) ideas welcome here too. I need ideas for a quick fix for the horsepower blues.

I know I should have bought the SRT but the deal on this was TOO good!

The driver, pun intended is that I will be racing against a manual Z4 3.0, with 30 Kilowatts more power and 80 Kilograms less weight that is driven by my business partner and NEED to kick his ...

Chips are OK but which one, PowerChip is here in AU so I can do that but is it in this boards opinion the best move?

So let your creative ideas flow!
