Hello all, I'm new to this forum and not sure whether I've put this post in the right spot.

I'm in Australia and have a 2007 Chevy Avalanche 5.3 LC9. I'm looking to delete AFM completely and also change the cam to a more "peppy" one than stock.

I have downloaded the demo version but can't see how you'd turn off AFM and remove the tests that generate DTC's P3401, P3425, P3441, P3449.

Do you actually change program code? Could someone point me in the right direction please?
