FICM Programmer Question
 

Corey/ Bill,
Just received my programmer. Thanks guys.

I was reading over the instructions and saw that I have to unhook any tuner that is on the truck.

I have SCT custom tunes, do I need to program the truck back to stock before loading the FICM programmer?

I would recommend setting everything back to stock, then reprogram the FICM, then reload the SCT. But I don't know that much about FICM's or SCT's...

I think that what I will do. That way I will be on the safe side. :thumbs up yellow:

That's why I recommended it :cheesy smile:
as the cliche says "better safe than sorry"

I've loaded the FICM tunes without returning my SCT/ECM to stock, no issues. I even let my buddy try the FICM tunes without returning his SCT/ECM back to stock.
