I still think your tuner has something setup wrong in the Pro EFI. EGTs are not going to be high enough at idle to make them glow red with everything else being normal.
For it to be glowing red it's going to need to be 1000* F or so. I've never sent a gasoline engine idle that high. Maybe more like 600-800. Especially if you are on E85
Try adding more timing anyway. Tell him to add 5* at idle and see what happens

things that can cause a P0507:
A vacuum leak
• Leaking air intake after the throttle body
You have an air leak somewhere after the throttle body. The air leak will let in excess air with no added fuel so the idle will be lean, fast and unstable. The lean condition causes hot exhaust and glowing headers.
