Lower Turbo Pressure (bar) like others problem

WRC cars turbo pressure difference.....

Hy all . I play the game for the first time and for me the turbo pressure all turbocharged cars lower like in multiple YouTube gameplay videos....Why? how can I set this setting?

For me the Yaris GR and all WRC cars run only  2,5 bar of turbo pressure and I see multiple videos with 3,5-4 bar off pressure.... this is the right pressure for WRC cars. I really like the game but lower pressure make the car lower hp I think.... 

Anyone can help me about it?

Thanks!
