Hi I’ve recently put on a stage 1 tune on my car and with a cts turbo intake but everytime I drive with the stage 1 tune the check engine light decides to turn it’s self on but usually stays away when I put a 0+ tune on it if anyone know what could be the cause it would be a great help and even greater help if you could give solutions but it even tried replacing the MAF sensor with no avail thanks 🙏
