We had deleted the rear o2s due to trouble codes from the high flow cats so that is ok. Took one of the rear o2s and swapped with a front today to see if that was the issue. It returned the same readings.

Those are good numbers for a NA 426. However, you add boost and it will look really amazing.
Are the internals forged?
