Does anyone know if there is a tuner/programmer available for the 6.0 vans?
I've had Ford E350s with the 5.4 up until now and SCT made a tuner for them so I was able to firm up the shifts and get a little better fuel mileage out of them as well. I'd love to be able to do the same with my new Express.

 

I have researched this to death, and can't find one. And considering that the same engine/transmission is in models that a tuner is offered confounds the daylights out of me. GM does state slightly different HP specs for this engine over different vehicles, so there must be something to that.

BTW, mine is a '16 3500 6.0 Flex.

 

HPTuners is what I use, covers my '02 Express and all trucks
so I'd expect covers your 6.0 van as well. And if not they often
will oblige you to extend coverage as they've taken apart so
many other OSes.

Check their site for detailed vehicle coverage list.

"Programmers" as in handheld are a waste of money and
are short of "reach" - shallow and narrow. Although the
SuperChips seemed to have more than most, again do
not know whether it extends to vans.

The other broad coverage GM tool I'm aware of is EFILive
but I do not know how much they care about trucks.

 

Just tried an HPI on my 6.0 this last week. it would not connect to my van. And also, I did call HPI directly. and they told me that the '18 Express (which is what I have) does not have any support at this time.

 

Maybe call a local shop to see what they can do?
