408 Magnum New Build, Gutless of idle

Appreciate all the replies and suggestions.

The Torque Converter does lock up. I didn't change anything with the transmission as I expected that the motor would require an overhaul in short order anyways and any necessary changes/upgrades would occur then.

I have a local HP Tuner that can dyno tune it and tell me what all is going on. As soon as I get my exhaust buttoned up and Wideband installed that's the next stop.

Will keep everyone posted. Really don't want to swap components but reckon that may just be what I have to do if the tune don't bring it around.
