I ran that setup everyday for about a year on my 06. s467.7/87/1.0 FMW. The 1.0 and 87 definitely made it feel like a much bigger turbo than it was but it performed very well on the top end. It would surge between shifts at WOT due to lack of fuel. I put a set of 100% overs behind it after and that made a huge difference.
It's a good setup! I only lost a few mpg as well. Maybe 2 or so. But once I swapped my injectors I dropped more. I think I get 15 city and 20 freeway now. Not calculated off the lie-O-meter.
