I did a 6.0 swap engine runs fine no check engine light but when you hook the truck up it has a u0100 code stored could this be a tuning issue.

sounds like a communication issue, possible damaged wire during the installation.
I checked all grounds an wires couldn't find any damaged. I'm thinking maybe it's a bad ECM.Quote:
