I have a 79 Camaro with a supercharged 2003 ls6. I have long tube headers and a ricks tank for the 79. Previously when the engine was in my 99 SS it ran great. Now I have completely different maf. I have an AEM wide hand AFR gauge.
The AEM gauge after warming up and while warming up shows 10:1. When I push the pedal to the metal, and then lift off it goes Rich.
I have changed the ve table, the maf table the injector open tables. The car is really rich. Pulled a spark plug and it was rich. I have pressure Guage on the fuel rail and at ideal it appears to be 60;psi.
I have searched this site and others, I have tried everything, and nothing makes any difference.

Thank you for your insights

These are both play files to get a change.

 

You have added fuel and are commanded it to be really rich in PE. It needs to be tuned.
