My car currently has the MP215 flash on it and I am contemplating getting an AP and a custom tune or run an OTS tune. As the title suggests, I am wondering if it is safe to reflash it with a protune/OTS tune or if I need to have the dealer revert it back to stock prior to doing this. Someone had mentioned in a different thread that you could brick the ECU by doing this as they run different firmware and I wanted to get feedback from anyone who has done this or is more knowledgeable on the subject than me.
