No idea what the issue was but I noticed that if I ran the A/C the engine lights would trigger. However if I turned the A/C off and drove 80+ mile (the amount of distance it takes to cycle the ECU) it would go away. So for some strange reason the A/C was triggering the lights. As much as I tried...
I only ask because I'd like to do it with an LS3 Erod. I have a v8 4th gen already. Granted a lot of work would need to be done but I'm curious if someone out there has already done it.
