I think sometimes the little things "can" make a difference. Like GM quietly improving their transmissions in the Equinox 2010. Made the tranny much lighter and mileage really improved. I think there is just a bunch of stuff we don't know. I wish some RAM engineer would give us the complete skinny across the line. Right now my 400 mile 2019 Crew 4X4 6.4box etorque hemi with ORG, susp, getst right at 15.9 on interstate in Montana with two passes to cross in 200+ mile commutes. Any idea if the engine is programmed to run differently the first 500-1000 miles?
