Great numbers, but it's a shame that the computer will simply adapt and put you right back at the first set of numbers. It will, however, give you a target a/f ratio to which to tune a chip. It is definitely $75 well spent.
Rick91GT, I'm surprised you think that's lean. 13:1 is what would be optimal for power for an NA car. It is interesting to see how rich the computer actually keeps the a/f ratio.
