Im pretty sure his dyno is tuned wrong/ wrong road load terms F terms. I saw his video. There is no way the truck is making 510 ft.lbs at the wheels. It makes 510 at the crank as per Ford. not at the wheels.
50 mph roll sport mode.

They do when its a redneck operated dyno, instead of a properly calibrated one.

I’ll trust reports from a vendor who relies on dyno numbers to secure customers……
I saw it too and have seen several other Gen2s and Gen3s dynoed.
If we even look at Hennesey's base runs:
Gen2 365/422
Gen3 361/458
This is closer to what I've personally seen.
That video shows +20hp and + 50ft/lbs torque, which points to a calibration issue. The Gen3 makes more torque, we all know that. But not 500* at the wheels. Nor does it have a 20+HP bump at the wheels lol
Peak numbers mean nothing when it comes to torque management algorithms in the ECU.
If the Gen 2 had it's nuts cut via TM for traction reasons, or to protect a particular component that has now been strengthened, or whatever the reason was- then the Gen 3 could very well have a ton more low end simply b/c Ford is not yanking timing to reduce torque output. I think the obvious thing to try is to flash a Gen 3 tune onto a Gen 2 and compare that to the same Gen 2 with it's stock tune.
The Vette guys have ben fighting TM big time for years. GM pulls a ton power in the lower gears to protect the IRS and transaxle.

Ok blind sheep.
He doesn't own the dyno. He drove like an hour to go to rent/use their dyno so he can do this spark tuning. That's all he did, advanced and retarded spark while keeping manifold charge temperature (MCT) in check.
he isn't doing some rocket science here.
Also, the fact that you choose to trust a random dyno shops calibration and tuning vs what the FORD OEM tells you is beyond me. You're truly lost.
That's more like it, I also agree.
