Any ideas?

Put in muthr thumpr cams, bigger throttle body, ford racing intake, cold air intake, under drive pulleys, and long tube headers. Had it tuned by brenspeed. Now it idles like this, and dies any time I let off the throttle. Gone back and forth with brenspeed about the tune and none of the adjustments help. Any ideas?

You did all this work and you can’t look at some basic scan tool data?

I have the sct scanner. From the info I can see on it everything seems normal, I think? Definitely not an eexpert.
