Probably you are correct, but we can not negate that the results that I am showing here were confirmed in 3 different dynos, dynos where BMW, GTR, MERCEDEZ BENZ, AUDI, WV and other cars with more power, were or are tuned, I apologize myself for the misconception I took about the joke, but focusing on the S280, it is not normal that most of the dynos here shows extremely different results that most of the peopel in USA have, and not only with the S280, but with the Whoosh Hybrid turbo, X47, and the master power that is above 400WHP with stock internals and gas mixed with boostane or race fuel.
sorry, but it is true, I do not know why is so hard to take the S280 above 300WHP in the USA, and here in Colombia most of the turbos in most of the places are higher than 315WHP
