hey guys I am helping my friend with his 2009 Shelby. It has a pulley, exhaust no cats , intake, heat exchanger and a few other small things. he insisted we based the tune off his old bamma tune so I did. the car runs great except under WOT the afr is 10.1-10.4 I want to get it closer to 11.2-11.4. I am used to tuning GM vehicles and not familiar with ford ecm. Where do I go to lean the WOT AFR? I figured out how to tune out DFCO pop. I believe at that rich WOT we are leaving a good amount of power on the table. Any help would be appreciated.
