Thank You for the help. I’ve got it set now and the truck is operating better than ever!

I had to go low, retarded to around 2/3’ to stop it pinging with regular gas. I read this was a Service recommendation years back to help with operating issues and it worked for me.

It also finally stopped idling too high on cold starts. Which it was doing at 5’ Now it idles up to warm up like any other vehicle. Around 1100rpm or so instead of 1400-1500

Only minor issue is the low idle (500) on warm restarts. I.e. restarting engine after its been running. It’s done this since I had it. Made a separate thread to look for help.

Funny enough now that the ac idle up works if the ac is on when i restart it idles at 750
