Hmm... I was aware that the direct-injection GM engines used lean-burn, but I am not aware of any conventional port-injected GM engines that use lean burn (in North America anyway).

For those of us running stoic, watching MAF flow is also a good indicator, as air-mass is directly proportional to fuel-mass when an engine is in closed loop.
