Honestly if you want more performance you're better off saving up for an M. Only other thing I would do to a 3.0 is better tires.

And before someone takes my comment the wrong way, the 3.0i and si are fantastic cars. If you love yours, you can mod the hell out of it (supercharger, etc.). However if you're simply looking at performance per dollar, an M is a better deal.
Hey man, I totally argree with you; with the amount of money one would spend to gain 100 hp would be better off just buying an M! In some cases it might even be cheaper and we all know it would hold value better too, But thanks for the input on the chip, I figured it was a little fishy. If ya dont mind me asking though what do you think of the cold air intakes? I know the one for a z4 is $350+, is it worth it you think? thanks
