Exhuast Brake

I have a 2007 6.0 f250 and do quite a bit of hualing with it. The tow/hual mode just doesn't cut it coming down a hill with 12 cows in my trailer so i'm thinking I need an exhuast brake. The one I am looking at is the PacBrake PRXB. I have a 4" MBRP turbo back straight thru exhuast. I'm not sure if this would be the right brake or if it will fit onto my exhuast system. Any advice/info/tips/comments would be very much appreciated!

Do NOT install an exhaust brake on a 6.0. In fact, it is specifically stated in the owners manual.

How many PSI of drive pressure is needed to lift the valves off their seat, I thought it was around 40 psi but I can't remember.

If you had stiffer valve springs then I don't see why you would have a problem with it.

I am on my iPod so I cannot see your sig.
Do you have an SCT? If not get one and get a tow tune with aggressive tow/haul mode and a turbo brake. That will help lots with slowing down your rig. There are a few site sponsors that write files for the SCT.

First, do not put an exhaust brake on the 6.0L, its right in the owner's manual.

Second, how heavy is that trailer with 12 head onboard?

I'll wager you're over the towing capacity with an F250. That could be part of your issue. I would recommend getting an SCT, with a heavy tow tune with the turbo braking and see if that helps. The exhaust brake is only going to devistate things under the hood.

When the dealer did the reflash on my 06, 6.0 it screwed up my tow-haul, when PHP reflashed my truck back to the way it came from Factory it now works like it should and I pull a 16.500 lb fifth wheel.
Has your truck ever had a reflash?

Exhuast Brake

Why exactly is it recommended to not get a brake?
Previously I was looking at a banks speed brake (which also uses the turbo as a brake) and was researching it with a diesel mechanic and he said that I would end up blowing my turbo since I am just manipulating the turbo to do something that it was not inteded to do. Has anybody installed this SCT on theirs? If so how is it working?

I pull a 24' ft stock trailer full of cows all the time, and a good tow tune really makes a world of difference. Does your trailer have trailer brakes, if not its a good idea.

I have towed with the turbo brake and my turbo has not blown up! If the turbo brake that tuners use with the sct, there would be lots of threads of guys turbos going bad. As to the tech that says that manipulation of the turbo is bad must not realize that we have a vgt turbo. The vgt is constantly "manipulated" when the truck is running stock. The whole reason behind a vgt is to be manipulated. There is a strategy that cycles the turbo veins to keep the unison ring from sticking.
Hopefully somebody that has actually used either of the banks or PAC, that can give some straight answers.
