I am pretty sure you either change the RPM where it starts registering missfires to a higher level or you can delete it. I think you will need LS1-edit though for either method.

Not sure with the Predator, but you can change the Low RPM misfire detection with LS1-edit to 32000 microseconds.

What I find funny is that the stock "microsecond" in the table is 32767 so how does changing it to 32000 help. I did this when I first got hp tuners and have still set the light. Wouldn't you want to increase that number to make it less sensitive. Someone chime in here because I don't really know what these values stand for, I just know that I tried it and it didn't work for me.
