I put the headers on with the SC.

Here's a dyno with AFR (notice change at 6750 rpm):

I have a BavarianTechnic scan tool (another toy to play with ) in the mail to determine if there were any discrepancies in the tail pipe reading since I do still have section 2 cats in place. I will be doing recordings of different aspects along with lambda (then converted to AFR) readings from both banks. Should be an easy fix assuming it wasn't simply a false reading by the dyno.

This is what I'll be doing with the BavarianTechnic tool: http://www.m3post.com/forums/showthread.php?t=723927

EDIT: AFRs fixed...
