sorry mate, not trying to knock your car at all so please don't take it that way, but it starts lean and doesn't make power until approx 120, almost looks like the operator had no idea and was just driving it before putting the foot down, so it does not show the low down power, they also have their own correction added to it rather than the SAE standard based on weather. It's good that you have had a go yourself and are wrapt with the results
