Those A/F numbers look like it is already tuned for boost! I would like to see what kind of power it would make at 12.5.
Also, the way the AF curve slopes down, it might have a "PE vs. Time" table that keeps on adding fuel the longer you are in it. I had that on my 04 GTP and it was a bear to tune.
