all this talk of remapping and tuning is definitely very interesting! But I fear that there may be the same issues with re-mapping a 325i (arriving March) as a 320i, i.e. not significant performance increase for the price!
What are the other physical ways of tuning the car? Like a air intakes (Gruppe M), or exhausts? It seems that this 'physical' tuning is much more popular in the US.
What would everyone recommend, besides software modifications??
