Thanks for the update / patches. I'll try to test them out soon. I think I'm going to park it until the alternator comes in though. I have an electric water pump and if I lose another diode in this heat it could end badly.

Strange they'd only do that on the y body. That's where 90 percent of driving happens.

Also worth noting are the constants at 126da and 126db that apparently dictate the transition points between using the closed, open and no individual trims.

If a tunnel ram has any redeeming qualities it's airflow at WOT. The end.

I'm sure they learned a lot from the mini-ram and it's no accident just about every intake design afterwards used long runners with the inlet funnels as far apart as possible. I would imagine it also had something to do with the LS engines' different firing order. Airflow dynamics are everything...

I'm sort of thinking it's an actual lean condition on the right side because I'm still fighting with hot restart.
