I just thought that I will see about 270-278HP or something like this not 255.
Car is nice and quick but from beginning after puchase I started to buy better fuel, changed filter to pipercross and thought it will help some.
After dyno they show me another i30N - 265HP - totally stock but I don't know what fuel it used.
Another thing - I saw lots of dyno movies with big air fan in front of the car.
I didn't saw it on this dyno point. The only air fan was used after first test to cool the engine after opening hood before second attempt.
I told them to set N mode before test but they told me it is not too important because all modes depend only from pressing the gas pedal (something about pedal blocking - in sport or N mode you can press it to the floor in others not - ? ).
It was weird but before second test I set them N mode on steering wheel.
Sorry for my english I still have lack of technical words when we talk about cars.
