Thanks for the replys! I really don't know much about this. I don't even know what an ecu is. I'm going to do some research and see what I find. I have a lease so do you still think its worth it?

I guess you haven't seen the RPI products. Read post #8 for details.

So thanks to the curse of this forum I am considering things I never thought I would before. lol Are there any worthwhile mods to make on the 528i that would make it noticeably faster without breaking the bank? I know about the sprint booster, scoops and love the idea of an rpi exhaust. I have to say I would feel foolish putting on an exhaust though when the car is not fast lol What is going to get this cars 0-60 6.9 sec time down? Or is it not worth it and I should just plan to get a bigger engine next time. Thanks

You sound like me when I had my 2007 525i.. 215 HP and 185 torque was pointless for what I was wanting out of a BMW.
After your lease, I would highly suggest upgrading to a 535i or a 550i.
