There's people saying all over the internet that the GT fuel pump will run lean for a 3sgte swap and a 255lp swap is required. Will I've been driving mine around for a month now around 700 miles. So far I'm fine. Punched it here and there. Here's a link to my video of my car WOT in 4th gear. You can see the A:F ratio yourself.

That video almost makes me wonder if somethings is off with my car now.... I have cams and no tune though so that may be my issue. My swap is running a 255 pump and your a/f looks the same as mine besides at idle. We may also have strange data differences because I'm at 5,000ft elevation vs you being at sea level. I'm at 14-15 at idle instead of 16 like yours. But besides that in hard boost I'm at 10 flat aswell. I say keep it just like it is.
