Check this out!!
 
They also have these..
 
I find it interesting on stock truck with MPT tune only they show roughly 60 HP gain but with manifolds it is 120 where as MPT claims up to 110 hp or so tune only on 93.

Also, I used ChatGPT to overlay the two dynos from each offering and you can clearly see the turbo lag from the larger turbos. The graph isn't perfect and I don't feel like messing with prompts to perfect it but you get the general point by RPM.

MPT is quoting flywheel horsepower and the Dyno is showing rear wheel horsepower but that only explains a 20% difference.

The difference between the curves is because high flow manifolds don’t have the same low rpm horsepower/torque as the stock manifold which is made for a truck and low rpm horsepower. Daily driving that “full-race” truck would not have the same “OEM drivability” based on those Dyno curves.

This video claims 453 whp on this tune. I think MPT is claiming whp, not flywheel.

Also, the difference in the curves would be the bigger turbos taking longer to spool. I would think the manifolds would increase spool, not reduce.

453 wheel horsepower on an ecoboost tremor with only a tune seems a little sketchy to me. But to each their own.

If you change the turbos and the manifold at the same time you can’t really tell which issue you are looking at. But a high flow manifold will reduce low end horsepower without changing anything else and a high flow manifold can reduce exhaust pressure at the same rpm which will cause the turbo to spool slower (boost vs rpm).

From their product description. I think they would know their product.

But strength is only part of the story. Inside, the Formline® design improves how the GEN3 EcoBoost breathes. Each runner is precisely shaped and balanced to smooth exhaust velocity and reduce backpressure, helping the turbos spool faster and respond more predictably
