I just bought a 2016 Camaro SS and was asking the service manager what mods I could get away with under warrantee. He didn't get deep into it but when we got to tunes he said since 2008 they could tell if a tune was done and removed for warrantee issues. What he did say though is that they only check the CVN number. His buddy has HPT and has figured out a way to tune under the stock CVN number so it doesn't leave a marker. I didn't get to talk to him much more about it so I figure I would post up here to see if anyone is doing this with EFI Live and how can I do it. This car is painfully slow and want to start my mods.
