Got this box in, waiting on AFE to send me a new lid(one of the holes doesn't match up with the box) and for my family to go on vacation so I can take the time to install it myself at the hobby shop. I really hope it gives me some decent gains on an otherwise stock N51 E90. Thinking of doing a baseline dyno before doing the install and then another to see if there was an improvement. I was able to pick it up for $450 from the same eBay vendor.
