I tried to upload a video and got some vague security error message. The ESS kit is a good one but I'm pretty sure mine was the first E89 30i that has the kit installed. It wasn't plug and play and I had to have them ship me some different parts and modified ECU tune to make it work. Ultimately, I had to take the car to a local BMW performance shop to get at tune that would produce the advertised (80-100) HP boost. I have about $8k wrapped up in all the mods to pull an additional 130 WHP over stock.
