A Gen2 2.7L ecoboost is rated at [email protected] RPM's and [email protected] RPM
If I understand this correctly, these numbers are at the crank. If all I want is the same 325/400 to the ground,
how much harder on my drive train will the extra boost be over the long haul.
I intend to keep this truck for at least 200K miles

What's more amazing about that 400ftlbs is that I think I read that the 2.7 is making 90% of its torque at 1900rpms. Or something similar to that.

It's an amazing motor and punches like a heavyweight.

It’s more so who is tuning the platform. There are many strategies to produce more power. Many big name companies are doing it entirely wrong ;)

When you say "doing it wrong" what are they doing, and who is doing it right?

Go with a reputable company/person who tunes thousands and thousands of these engines, Stay on top of your maintenance and you should be good to go. Seems most of the people who have issues with any company (well except one that's 3 letters) are pushing their trucks to the limit, running at the track, full bolt ons and whatnot.

Honestly, getting to 325 whp/400 wtq is probably not that hard. These trucks dont seem to have a lot of driveline loss.

The stock 2018+ 3.5L with 375 crank hp could make ~350 whp on the stock tune on 93 octane. I bet your 2.7L on 93 would be pushing 300 wheel on the stock tune.

Yeah going from 325 crank to 325 wheel isn’t that hard at all. If your at sea level all you need is like a 91 mild tune

I do not want an argument on who tunes better, no any arrows tossed at member tuners. Everyone picks according to their own criteria. But Brew City Boost did run a bunch of dyno results on the 2.7 platform recently.

Their canned tunes,

and a compilation of various tunes.

Tunning these vehicles is not a close kept secret and there are a lot that can and do duplicate these results.
"all I want is the same 325/400 to the ground " seems quite easily achieved with a simple canned tune, exceeded with a 93 octane performance tune.
I own a 2017 2.7 with BCB tunes. Have run the Highlander and custom 93 since very early 2018. That is close to 40000 miles without any reliability issue or any problem at all. I am an aggressive driver most of the time and like to push it. KM

If I’m running 17-20 psi, varying at times, does that mean I’m at the limit of my turbos? I’m at 31-32lb/min at 7000 feet.

Looking at WasteGate duty cycle will give you a better indication of how hard your turbos are being pushed. I would say for that elevation, you are doing great in the airflow department.

At wide open throttle I’m about 28% wastegate percentage.

Then, not much left. Most tuners don’t like to push it harder than that as you start Over spoiling.

I thought when you are 90% or more is when you are overspeeding

I’m saying that when I’m at wide open throttle the wastegates are only 28% open

28% is really 72% closed. It’s kind of backwards compared to the 12th gens.

Dumb question #567 - in OEM form and tune, do the wastegates open 100% under full throttle?

Not that I’ve noticed. But right after you let off they blow to full wide open
