2016 Silverado 3500 - Ike Gauntlet Pull
Looks like the Chevy still outperforms the Ram on the time up the Gauntlet and more importantly outperforms in exhaust brake performance too. Link

Yes, but as I stated they put the truck in the wrong exhaust brake mode. Pressing the exhaust brake button one more time would have put it in auto mode which is the mode you want if you want the truck to keep a certain speed and not mess with any manual shifting. However they had it in full mode which is the mode that may require you to downshift gears manually in order for the exhaust brake to be stronger. Ram's auto mode is the same as Chevy's standard mode that will automatically downshift on its own to make the exhaust brake stronger if the truck starts going over the desired speed.
My 2013 in full mode downshifts and applies full exhaust braking. The exhaust brake on full always tries to slow the truck at a curtain rate no matter what the speed. If the truck is not slowing down it will put out 100% of it's capability and will down shift when able to do so and not red line. In auto mode it does what it has to to hold a curtain speed. The two modes put out the same braking force.
The point I'm trying to make is that if the exhaust brake has enough power to hold the truck it will do it in either mode. The only difference is that in full on mode it will continue to slow the truck until around 20mph. On auto mode it will slow the truck until it hits the set speed then adjust it's output to just hold that speed.
