Better Braking

Hi all,
As you all know I'm trying to get the DEMU just right, just tried her at speed and used the emergency brake to slow her down where I wanted it to. Does anyone know of a way of adjusting and what to adjust in the .eng file to do so please?
Thanks
Andy

I think this is the section that I need to adjust;

AirBrakesAirCompressorPowerRating( 1.7 )

I thought I would come back to this as no one has come back about this and I think this would be an important piece of information to put into the HFL section??....
Any thoughts everyone?
