It would be interesting to see this graph displayed against RPM instead of speed, and also to include Torque since that is typically what you will "feel" the difference in. I'm also a bit concerned that it looks like the tuning may have been done at the expense of leaning the car out. Your air-fuel ratios get down around 12, which I personally think is a bit too lean over the long run. If those only occur occasionally at high-rpms, maybe it isn't too big of a deal, but running too lean for too long is a great way to destroy an engine. I do admire how the stock tune stays right at the 12.7 ratio pretty much all the way though... car manufacturers are notorious for tuning cars on the rich side to build in a margin of safety, but this appears to be right about the optimal line.
