Techron?

I'm being forced to use premium fuel on my truck, to avoid pinging like crazy. Guess with that, no need to use Techron (or any other additive) anymore. But boy, will it be more expensive, as the difference between regular and premium gas here is $0.60, so around $20 extra every tank. Regular fuel also has additives, but I don't know how much less than premium. Does anybody know for certain? Just curious about that.

The additive packs are confidential. However, if you run Top Tier gas, at least you have a guarantee of a minimum amount of additives.
I run premium in both my EBs, as the performance is substantially better. The government study that got posted recently claimed a 0.7sec improvement in 0-60 times burning premium. That's a pretty substantial improvement!

It's more a matter of the tuning and cleanlieness of the burn in the cylinder. so under around 85F - or lower then I use 87 octane or 89 octane gasoline. Why - colder IAT (Intake Air Temperatures) let the engine lean out a little as it works with the 87 octane gas. Octane rating is all about knock and the way the engine runs on 87 is that it starts by enriching the mixture with IAT and at some point it begins to retard the spark timing - and in the ecoboost engine you can vary the valve timing as well as reduce the boost if there is less load. All of which can contribute to running richer to protect the engine which contributes to potential soot buildup.
Colder temps - 87 octane matters not. Hotter temps 93 octane helps significantly. But as I remind people - matter of area. I live in the midsouth USA where in the summer we will have 90 degrees F and 80+ % humidity. Ecoboost wants 93. I gain MPG when I move to it and the engine runs better - however I get the same mpg in January on 87 octane.
Hope that makes sense.
No offense but he was attempting to direct the information to the question of the thread. TO be fair for this OP the multiport fuel injection on the new ecoboost doesn't help him right here - unless he's buying a new 2018 model.

There's a load timer as well as the EGT modeling that results in Lambda that looks like a slope as you rev out the engine. It runs literally 1.0 lambda at lower rpms and richens up as you rev, to the point where if you're in the throttle for longer than 2 gears at wide open throttle you're running .68 lambda (10.00 AFR)
IAT compensation is not what you're referring to. IAT compensation exists solely to make sure as temperature changes your AFR is still accurate.
On 87 octane the ecoboost engines never get over 2 degrees of ignition timing anywhere under wide open throttle. In fact most of the entire rev range they're around -2 to -8 degrees of timing.
YMMV on the gen1 ecoboost motors, since they're 100% DI they most likely run more ignition timing than the new ones do.
As far as 93 vs 87, the ecoboost will benefit greatly year round, regardless of temperature. IAT being lower will result in higher base timing since there's less immediate ignition adjustment based on iat.

I wish what you were talking about made sense, but the only thing that richens lambda in the OEM tune is exhaust gas temperature modeling and catalytic temperature modeling based on the Estimated EGT's. Truck doesn't have an EGT sensor but Ford put in the work to model it in the lab and setup tables that actually know how high EGT's are based on load and a variety of factors that they modeled in said lab.

Will running 93 octane in a '19 F150 5.0 make a little more hp with no mods or tune. I always run 87 with no problems but occasionally take the truck to the drags, run around 14.5 @ 95 mph on 87.

Seafoam in the gas tank would have zero negative affect on turbo's...adding it to the crankcase is a different scenario.

Just so you know, It would be 2017 3.5 EB model or newer. Ford starting using the 3.5 EB Gen 2 in the 2017s

Yes, on 93 i would expect you to run like a 14.0 @ 97-99 mph on 93 octane.
