Sounds like an easy enough mistake. And I'm sure you are not the only one to do it. Again, glad you got it worked out.

Yes all 13up trucks have that module. Most guys unplug it and remove it when they change the exhaust out.

In a nutshell, it all depends on how, in this case, the EFI Live tuner makes the tune in order for what has to removed or unplugged. Some guys just block codes within the tune to achieve the desired result, while others remove the logic out of the tune completely.

OP, you should not need any of that BD equipment with EFILive either. If raceme custom tuning is anything like smarty udc, it leaves much to be desired but we shall see.

Yes sir we don't like the current UDC much either. Hopefully it gets better with what is coming.
