I second this. I was running an OTS Cobb tune, had the dreaded cam phaser start up mating call, pulled the tune and went to the dealership. They said nothing (my understanding is that they can tell when you've reflashed the ECU) and I was able to get the work done under warranty (including a short block replacement).Technically - yes, but depends on your dealership/service department
