I think that Run#1 (red) is the stock engine graph....the values given are WHP at different speeds.....And Run#2 and Run#3 (in green and blue) are after ecu flash....
From what I understand at a given speed the WHP value is much higher after re-flash as compared to stock...so that is probably showing better low end torque....
e.g. at 100 km/h the stock is giving 50 WHP whereas reflash are giving 87.9 and 80 respectively....
I could be completely wrong though....
