I am not a tuning expert. I think it is subject to a lot of things, like the optional equipment in the car, road conditions, tyre, weather etc). Even standard ///3 are different to one another, so when you tune it, again it's going to be different similarly tuned car. I have seen on the dyno a few times. It's very interesting.
Hopefully, experts like Mike can enlighten us as to how all these conditions impact on the power output of a car,
