At low RPM's there is less air being moved thru the motor, making ANY exhaust brake less effective. The fact that the EBPV is one of the weakest exhaust brakes you can use (I am a fan of them, dont get me wrong) it makes it that much less effective.
They work on back pressure, you will have less back pressure with lower RPM's
Also at lower RPM's the trans pump does not have as much pressure built, which makes it harder to keep the coast and lock up clutches locked up.
How is Jody "protecting" the tranny? If its just locking the TC thats what the SP Diesel unit does as well.
Thats what I loved about my SP Diesel kit. On the gas, its off... Off the gas, its on. All controled by my cruise buttons. Could set my TC lock up speeds to where ever I wanted and unlock speeds as well. It was a slick unit!

You may want to hook up a tranny gauge and make adjustments with tuning software and see how much you can adjust the pump pressures.
There's more to tranny tuning then just TC lock up.

Sad thing is the pump is not a constant output pump like you might think... it will not put out the VOLUME of oil at 1300RPM's like it will at 2200RPM's.
I have a trans pressure gauge... I know what the pressures are at 1400 V 2200... and I know what they do when you let off the go peddle and let the motor slow you down.
Keep the RPM's up, your tranny will thank you, and your exhaust brake will work better.
And lets be clear here before I get banned again, this post is about EBPV brakes and there proper use, NOT TUNING...

You are as always very correct... You can bump the trans pressures VERY high with tuning... Its great on the pump of the tranny too...

Joe,
I am not perfect and at least I admit it when I am not.
No Joe it's a question about a tune that Jody created and what people have experienced.
So having a trans pressure gauge you know what the SP Diesel kit is doing to your trans?

Wow, I am really dazzled with all this info. Being techno challenged I just wanted to know if the tune owners are satisfied. John Wood is rebuilding my tranny Tues. When I made the appointment he explained to me all the advantages of the DP Tuner and I should consider the Decel tune among others. I figured since he is one of the top tranny build guys and he is praising DP products I will listen.
Anyway, thanks again for all the info. Bill

I love mine. I don't haul as much weight as the OP is talking about, but I have a 3 horse bumper pull loaded pretty good, I have a 7700lb dry weight travel trailer that I have hauled through the mountains of Tennessee and there are some really decent grades, and I have pulled many dual axle trailers loaded with all manner of equipment, as well as dump trailers full of crap. I also have an all steel with wood floor 2 horse trailer that gets loaded pretty heavy. I have my decel tune between my 60T and 80E tunes. I find that it works quite well.

I do like my decel tune, but I have to say that when I tow I don't find that it's all that great. It's better than nothing, but nothing like a true exhaust brake. I don't know how to explain it really, but at lower rpms like Joe said it's not very effective at all. So if I start down a grade at 55-60 mph I still pick up speed pretty easy. But if I start down the grade at 70 or 75 it doesn't pick up much speed. It works best if I kick it out of OD and get the rpms up, but then it's screaming at 75 and who wants to have it like that for a 2-3 mile grade?
So without going in to the tuning and how it works (because I don't know) I'll just say that in my experience the EBPV is a poor exhaust brake but if you have it go ahead and use it; I'm sure it helps some. But it's not enough for me to want to keep it so I'm going with a 1.0 housing and high flow outlet (non-EBPV). I'll still keep the decel tune and use it because of the transmission strategies in the tuning. I have wondered if that is actually where most of the benefit is anyway? Maybe Diane could elaborate on that.

I think it's great for the price,like Keith said not as effective as a true exhaust break which BTW is close to $1000. bucks, but it works.I Tow a 12000lb boat down a 6% grade and have to turn it off because I'm going to slow.For 45.00 you cant go wrong.

After all, what is an exhaust brake? A metal flap inside the exhaust system. Using the EBPV is just the Walmart version of a $1000-1200 add on. And a purdy slick idea IMO.

wow, i have the tune, can't say much about it except it doesn't work with the EBPV delete....May (probally) help the trans but doesn't slow you down any.. i got it with the package after the delete so i dont know about befor and after.....Hopefully i am going to get Jody to reflash my F5 at RRE ( for me only 19 more days!!!)

If you're towing 12K down a 6% grade and find yourself decreasing speed then I'd say it's working pretty well for you. I don't know why I don't experience the same thing, wish I did.

I had one (not the DP version but the SP Diesel version) and loved it, but it only works at higher RPM's where you can build back pressure.

even when im empty it works well down to about 35mph but the tc stays lock till 28mph but like you said not as effective at lower speed.
