Thanks Matt--I know that you are not afraid to try anything. I always like to hear the results.I was thinking about going the tuner route but, I want to slow the truck not speed it up. With a tuner I know I would have a hard time keeping my right foot off the throttle.

well, this is how i see it. backpressure is measured in the manifold and the ypipe. now, with the 6.0 turbo, the turbo does not have a wastegate to relieve excess backpressure like the 7.3 did. now, if you activate a exhaust brake the pressure overloads the turbo with no place to go, therefore i see the turbo being the weakest link. i have heard the valve train cannot handle an exhaust brake since day one. but what fomoco states and what is real i have found out to be different like night and day. i know the turbos can hadle around 50 psi of pressure as i have seen that much before. depending on how it works and how fast it can open to let off excessive pressure, will determine on whether it works or not in my eyes.

BowTieHatr---Thanks , And I do value your opinion as a tech. As I see it There is still alot of research to do. So if I were to monitor a pressure gauge and never let it get past 45lbs would you think that would be safe for the turbo? I also wonder how much back pressure there is when using the sct with the agressive tow tune?

If I am not mistaken, most of those devices are limited to ~40 lbs of backpressure. It might be a good idea to ask someone at the company you bought the brake from to see what the max backpressure is.
Curtis is right; extreme backpressures could possibly lock the unison ring or other moving parts of the turbo up.... but I would imagine it taking ALOT of pressure to do so.

Matt---The max back pressure is 45lbs. When it reaches that pressure the valve opens up to spill off excess pressure. That is measured at the brake which is remote mount just behind the cat. So I don't know if there would be more pressure at the manifold? They do have a gauge that I will probably get that measures pressure at the brake.

Gauges are always a great idea, especially the EGT gauge!
The BD Exhaust Brake is regulated with our variable orifice technology to insure it will not create too much back pressure. With that being said back pressure is still a great thing to monitor, it will help you set the brake up for maximum performance. The back pressure will change a bit as the carbon builds up on the butterfly so again the gauge is a great idea!
I would recommend looking at the BD Power X-Monitor http://www.bd-power.com/ford/product...Gauges&tt=ford
The X-Monitor will monitor Pyro / Boost and Back Pressure all in a nice compact digital format, it has the capability of recording maximum values and setting alarm setting features.
