Yeah, 2015+ 5.0 F150s are speed density and fords math for that is pretty complicated.
But as more and more of these new Fords are going speed density we will end up with more tuners doing them.

TX-Ripper,
I am still running the stock 3.725" pulley and though about moving to a 3.5". Have you done this and will the stock fuel system support this on 93 octane?
I am still waiting on my OZ HP Tuner tune. It has been a month and HP has not added the latest Whipple tune (which I have) in their software. Ken has a support ticket in with them but we are low on the priority list since they don't sell as many F150 Whipple tunes as they do other vehicles. Since I can't go backwards on the Whipple tunes I am stuck for now.

Yes. MAP sensor instead of MAF sensor. I just call it that because for me it was all about the sensor. Procharger told me it was equivalent to a certain car model sensor and it was not. It took 10 tunes to find the right tables. The first few he redid thinking he was doing something wrong. Then he just started trying different tables until he found the right one. It ended up being the same as a Mustang ecoboost 3 bar sensor. There was no part# that made sense to reference. Fun times.

I would ask oz about the 3.5, I don’t think it will work well without longtubes and no cats
or e50-85

The 2015-17 truck really needed the extra airflow to make power and got away with a lot due to the lower compression.
The 2018 is a lot less forgiving and playing on the edge of knock (think cylinder pressure and combustion stability limits) with this motor will cost you.
You can can ask Dustin Whipple but I believe they found out the hard way with their 2018 mustang testing.

If we could run 100% direct injection this would not be as much of a problem.
The current limit is 70%di and 30% port at wot with gasoline
And 60/40 with E85

I questioned that early on and everyone said the DI would make it possible. I was talking to Eric at ID a couple of days ago...he was saying the same things about the fuel system and how it’s really ran right to the edge of what it can do. Combine that with the tiny heat exchanger and intercooler on the new Roush and it’s even worse. I’ve seen a few guys saying their cruising IAT’s are in the 180 range.
