Interesting Quirk
So like many of us, its been really cold lately.
It was 5F here after work today. After startup, the 3500RPM yellow line became a fuel shutoff point upon quick acceleration. I tried it twice to see if it was an anomaly (it wasn't).
FYI - I wasn't trying to drag race or anything but needed to accelerate into traffic quickly. Interesting engine protection feature.

^^ I'd guess it is similar. Just one more way for GM to protect its (engine warranty) investment. Think of it as a cold-engine "lane departure alert."

When its extremely cold outside, the yellow line becomes the fuel shutoff point for the first few minutes of driving. This is different from when its warm when the redline is the fuel shutoff point.
Its just a weird nuance I wanted to share with the group. Like everyone, I don't generally redline when the engine is cold.
