Engine braking Gas Vs Diesel
Just wondering why gas engines have better engine braking than diesel. No real reason, just wondering. With the higher compression of the diesel I would think that diesel would be better but understan...

2008 - 2010 were the only years that Ford used a compound turbo. 2011 - 2014 used a single turbo with a double compressor wheel. The desired effect was quicker spool which it does. Two downsides are reduced engine braking through turbo vane control and running out of air at higher altitudes. So, in 2015 Ford went to a larger single wheel turbo to get more torque, more HP, more go at high altitudes, and more slow coming down the mountain. Repotedly it does spool slightly longer. I don't believe that Ford ever had an exhaust valve style brake; just vane control starting in 2011. I find that my 2012 works just fine in tow haul mode with cruse within 10 mph of the cruse setting. So just set it 10 mph less than what you want to max at as you crest the mountain. You do need to be able to watch the rpms run up toward 4000, but that is where red line is.
