This is with the assumption you are running factory boost. The engine and the ecu program are designed for the condition. Otherwise they could not warranty it. My former SRT-4 was exactly the same.
Good point. I was under the impression that the ecu would request a richer mixture at the higher boost levels, by that's not the case with my tune. I'll just have to get used to seeing 10psi+ and a 14.* A/F. It's a little unnerving to me.
