It may just be that other company s turn the cel for that code off. The code is for exhaust gas temp too low for cold start. My guess is that the tune stops the cold start fuel dump used to heat the cat up quickly. This is only for emisssions and doing away with it would help with fuel economy. I would not worry about it. If it bothers you that much just get a custom tune and have them turn that code off.
