I just bought a 97 "M" ti, I love every thing about it but I could sure use some more ponys! without going to a supercharger or an engine swap at this time how can I uptain some significant power? Or is it even possible?
Just save up and get the DASC if you want to go faster. That will be the best bang for your buck and it has a great reputation.
As for me, I doubt I will ever go FI on the bimmer, simply because if I had $3k sitting around then I would go buy a bike instead of a SCer (always wanted one and my dad said if I pay for it then he'll insure it).
