Towing and EBP

I have what some may think a crazy question but I'm gonna ask anyway. I read on the forum a little while back that high rpm and low or no boost can cause too much back pressure. When we come out of the mountains pulling our 5er(10000 lbs.) I always let the engine do the biggest part of the braking , usually up around 3000 rpm , the grade is about 6 percent for about 6-8 miles. Since the engine is breaking and not pulling there is no boost and I know that the back pressure is whats causing the breaking , is that enough for concern? The engine/trans was designed for such ,I was thinking. My concern is bc my egr is deleted. And of course I tow on no power with my H&S.

Well since you're not on the throttle while descending the hill you will be fine.

Ok thats what I was thinking. I think the thread I was reading was meaning high rpm (accelerating) with low boost was bad. I think that answers my question though. Again thanks for the response.

No problem man. Yeah that really applies if say you're hauling but on the hwy and you're turning some high rpm. The ebp's still wont be dangerously high but they wouldnt be the ideal 1:1 ratio they would start to get in the 2:1 or higher
