I've seen several comparisons of the XFi drivetrain design vs. regular 3-cyl Metros, and have never seen lean-burn on the list. I think if it did have lean-burn, its numbers would be even higher than they are.
Would lean-burn require a 5-wire o2 sensor, for example? Both the XFi and non-XFi share the identical part there, and it's a 1-wire affair (for a '94 Metro, according to the rockauto.com catalogue).
I've raised the question at teamswift - maybe someone can answer definitively.
PS - anxiously watching this thread to hear about Dan's trip...
