I have everything ready to read and modify my tune, but before I flash the original ECM, I need to know if the dealer can tell if I follow the below procedure.
Read my factory tune.
Save it as OG_Camaro.tun
Modify it, save it as Mod_Camaro.tun
Write the modified tune to my ECM.
IF the car goes in for warranty work, flash the OG_Camaro.tun to the ECM before I take it.
If they can still tell if I do it like that, I'll buy a spare ECM.
