I'm less concerned about peak horsepower than the area under the curve and the increase in the available torque which although it's not lacking on the stock ST, the torque curve is much larger with the tune.
It's the area under the curve that really matters, and it's looking pretty nice so far, although there aren't numbers on that version of the chart.
