I want to make some performance upgrades to my 2015 Trbo Regal. Trifecta Flash, doesn't regester when the dealer reads the computer. I've heard that you can't change/upgrade the air box or filter. Methonal injection? What can you do? I thought about asking my dealer but I don't want my car flagged so that they are looking or things.
This is my daily driver so the warranty is important to me. Anyone have any knowledge of this?
