Dealer replaced the MAF sensor saying it was bad.
Well, 25 miles between regens at 75 mph. Takes roughly 60 miles to regen then the ~ 25 mile clock restarts.
It's roughly twice as bad now as it was before they replaced the MAF. This makes two dealers now that have looked at it. It's now back at the first dealer.
The 7.3 gasser Ford is looking better every day. I can't believe two dealers, one that's extremely well regarded large dealer, have no clue as to what's wrong. This pretty much tells me the days of diesel are pretty much over due to the crazy complexity.
Never ever should have sold my flawless '18, this truck has had numerous problems.
