2021 Sierra with 5.3 with DFM. Is there a way to tell how many cylinders you are using at any given time. My 2019 Acadia V6 lets me see when it goes to V4.
I don't know about the 2021's but on the 15's if you leave your dash readout on the mileage setting it will show V8 in the lower right corner and when it shuts down the 4 cylinders it will show a green box with a V4 in it.
