You're lucky if you DON'T have a VGT and you don't want one either. Get an in-line exhaust brake. I've had a Pac brake for several years on a previous truck and now a BD exhaust break for a few years and they both work great. It also sounds like the electric operated brand works well too. I want on board air no matter what so I use the compressed air operated inline brakes. Craig

Not sure I’ve ever seen or heard of anyone adding a traditional exh brake downstream of a vvt.
Of course could be done physically and be operational, but it’s not common
Get a module, plug it in, take the easy route and enjoy a nice exhaust brake function without ever touching the exhaust or doing any re-wiring.

And yes I would absolutely do it.
The 3 big advantages of a diesel pickup are fuel mileage, more power and exhaust brakes. $500 is money well spent on a module to get the most out of your setup.

But he does, so what’s your point?

I’ve had the BD Diesel turbo brake system for quite a few years. Mine has 4 total settings...Off, Low, med, and hi. I hardly ever use anything but low and I would definitely buy again. It’s my understanding that now there are only 2 on settings on more recent units.

From what I've read adding a down stream regular exhaust brake can net around 160 hp for braking vs 320+ hp for braking using the EFI live tuning for the VVT Dmax. The computer changes the variable vanes for more aggressive exhaust braking.
There are several GM diesel forums with tons of input about EFI live tuning for the Dmax. Check out a couple of them for more input from actual GM Dmax owners who have used the program.
