Also wondering if the ECU is hard coded to limit to 8000. It still hits the limiter there even when set at 8300. But there’s a drivetrain abuse table that you can’t set over 8000 so I’m wondering if that’s what’s doing it
I've read the gen 3 LS1 ECU is hard coded to 12,800 rpm, but tables cannot be changed past 8000rpm, so you end up using the 8k table until the hard code stops you.

Yes, that is true. However there seems to be conflicting stories on where the hard code actually is. The rev limiter is 12,800, but the drivetrain abuse maximum is 8000.
Hammer I believe you are limited to 8000-8200 on the stock PCM. I have read some threads from others who ran into the same thing with their NA setup. I love when people are this meticulous with a car. Props to you, Darth and the tuner!
Thanks man! I mostly tuned it myself this time with some help from earth. He’s a good teacher. Lots of patience!

I disagree. Not to mention you can disable it via speed threshold. I've seen no table in EFI Live that says you can't rev above 8k on a gen 3 pcm....the only caveat is that you will be restricted to the 8k RPM row/column for fueling and spark. But if you're trying to shift right at 8k it shouldn't matter anyways.

There’s really not much to port. The base matches the heads really well and the CSA of the runner gets so big so fast I’m not sure it’s even necessary.
