Cylinder Displacement Sensitivity

[CHOO CHOO]

Is it possible to adjust to the cylinder displacement sensitivity? It seems like my tahoe only goes into 4 cylinders when i'm goin' down hill. Even on a flat surface it seems like it is too sensitive and just switches back to all 8 cylinders. Is there a way to change the sensitivity so it stays in 4 cylinders longer?

You need a custom tune to do that. A BBP tune can fix that
