how do i tune my cars so they have more BHP?

do i have to unlock this some how, if so how ?

Add the car you want to tune to your "Favourites", then go to race with it but when you select the green tick box, click the grey one instead, that's "Quick Tune". The only way possible unfortunatly.

Also, it's only possible to do this during a time trial. Unfortunately you cannot add power or reduce weight when you're doing a race against AI.

But lets try and keep all this in the established thread.
