Bill's 02 Z-28 SS

Hi Folks
Finally welded the bung for my LM-1 WB sensor. The result surprised me - first, I did not disconnect the air pump but from past posting it is only used during the first couple of minutes of operation. The numbers ranged at WOT from 10.9 @3K to 10.1@6.2K. I was surprised how low they were and was wondering does these numbers appear to what other folks have seen?? I know I have to adjust the PE but when I calculated the numbers, I went from 1.389 to 1.068, that is a big jump. sounds about right?
Thanks
Bill

1.15-ish gave me the 12.8:1 I was looking for.
But this depends to great extent on how true
your MAF and injector tables are. 1.07 I think
would be pretty lean.
