I know the knowledge is out there somewhere about how to edit the ECU for the 4.9, what I want to know is how difficult it is to tune the 4.9 with the tunercats software? What will I need? Any tips? I know illumina was looking at this at some point for the turbo build but didn't like something about it due to the unique needs for a turbo 4.9, but I'm staying N/A. So basically, if anyone's used the software for anything, not even necessarily a 4.9, I'd like to know how difficult it is to use, what I'll need, etc.

Thanks in advance.
