Brian, good luck with getting the AEM sorted out... I am bummed that I missed out on the track day, but there were to many unknowns for me to drive 1200 miles round-trip for a track day.
I'll hopefully sort out the loosening 02 housing this winter. I'm still needing to have the DP bracket modified so I can mount it to the tranny... this will help, also being able to secure all 5 nuts from the 02 housing to the turbo would be helpful

. Using any type of locktite isn't going to help due to the high temps.
