Make sure you get a chip to take the cylinder deactivation out! My wife's had that and it starved the cylinder on the left bank of oil and had to rebuild the engine.
+1. The easy (expensive way), get the delete chip from Range and plug it into the OBD port or do it the cheap way and unplug the vacuum modulatiion sensor on the power brake booster I did it the cheap way. That sensor sends a signal to the ECM to initiate deactivation.
In theory a great design but the engineers didn't look down the road at what it does to an engine long term. GM is good for not looking at the long term impacts of gimmicks.
