I have a 2007 Chevy Silverado 2500HD Duramax w/ a Edge Programmer. I want to add a K&N CAI, but they say to disconnect the negative battery terminal to reset the ECU's. My question is, if I do so. Will it erase my existing settings on my Edge Programmer after I'm done connecting everything back up, or will it stay the same and I won't have to fix it/ or change it back to what it was in the first place?
