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

Even the 6.0 PSD had exhaust braking through the VGT (only in tow/haul mode). The 6.4 PSD used a dual turbo setup which I believe only used fixed vanes and lost exhaust braking. The 6.7 PSD returned to a VGT and got exhaust braking back. Since its introduction the turbo tuning and size has changed, but all Scorpions have exhaust braking through the VGT.
