Changes to the Jack Brake in 2015 Models

Hi Everyone,

I'm new to this forum.

I've been researching a new truck for over a year now, however this year we intend to buy!

One thing that has kept me away from the Ford F350 and has been the Jack Brake.

From what I understand the design of the Ford Jack brake (engine brake) up until now has been shall we say 'lacking'

But apparently in the 2015 models they have re-designed the brake and it now works in a similar way to that of Chevy. I think it;s some kind of variable vein in the turbo..

And that is the lead into my question…

Does anyone know about the design improvements and can explain them to me?

Thanks!

Jake brake hasn't really been "needed". The Tow/Haul function works quite well to hold and downshift the transmission for downhill descents or braking when loaded. I'd have to ask around if its being added on the 2015 trucks.
