best ECU upgrade for X6 50i?
I wondering what everyone thinks is the best ECU upgrade for the X6 50i? I have a 2009.
I live in Australia, so its hard to get to a lot of the well known performance shops Im reading about on this forum. I want to get my car over 500hp and hoping to get there with the right ECU upgrade and exhaust. Thanks for your info |
