Installed mine today. Everything from the packaging, through the instructions, to the fit and finish was really impressive. Outstanding product. Didn't get a chance to drive much more than around the block, but initial impressions are positive. I had some decent off idle throttle lag at first, but it seemed to slowly iron out as I drove. No other issues that I can tell.
Well done!
I'll be jumping on a Mustang dyno next week...
