The L86 and L87 are actually 11.5:1. One of the tuners here on the forum, I believe it was blackbear, stated that in data logging even the 5.3 at 11.0:1 compression ratio had significant knock retard running 87.
NWI Denali started following 2020 Chevy Silverado Updated - More Models Get 6.2L, Show Us Your 2019 & Up T1 Pictures !, 2018 LTZ Just died and and 7 others
Duratracs are actually known for having squishy sidewalls so it was most like the tires contributing to the ride characteristics you noticed.
Gas engines today are so good with direct injection and variable valve timing, and these 1/2 ton Diesel engines are 10 years too late. I don’t see many people checking that option box. Does ford even sell any of their f150 diesel?
When the 6.2 has only been offered in the top trim levels the previous 6 model years, I would call that a Hail Mary to drive lagging sales lol. It’s a move GM has had in their back pocket for years, because it requires literally zero tooling changes to mass production lines. They chose to play it now because of terrible 2019 sales and losing the #2 slot to Ram. I bet we see a SIGNIFICANT interior redesign for a mid cycle refresh in 2021 like they did for the front fascia on the 2016’s.
^this. GM is throwing up a Hail Mary.. which may indeed work at boosting sales.
Wondering if the 6.2 will be detuned to run on 87 or 89 for the masses in these lower trim level trucks? It’s about damn time though. GM has had this card in their back pocket for years waiting to play it. I wonder if this is an emergency knee jerk reaction to their slowing sales on the T1?
