Do we really think the ported manifolds are going to do a lot with the SPD downpipes on stock tune? I mean another 50whp would be fantastic

I have a whipple on my R but after how much I gained with the downpipes before hand throttle response wise we shall see. I will try to get some dragy before and after data on the ported manifolds.

I'm looking forward to seeing some results as well.

With the downpipes, you're gaining two things:

1. Increased flow obviously
2. A more resilient cat that's also higher flow than stock

By resilient, I mean the that the cats don't overheat like stock.

Below is a shot of the factory on a 2023 Raptor R with 8,000 miles on it and the stock supercharger.

You can see how the exhaust flow is only using 35-40% of the overall cat area and creating a hot spot. This will effectively shorten the life of the factory cats. Add an upgraded Whipple supercharger and the factory cats are on borrowed time.

The second thing about resiliency is that the SPD Alpha Cats dissipate heat better than OEM. These trucks monitor everything. As the cats heat up, the truck will monitor and cut power accordingly to keep emissions in check. With the upgraded SPD cats, they handle the heat while keeping the truck compliant so the truck doesn't detune and doesn't cut power.

It's like upgrading the intercooler on an EcoBoost truck. The upgraded intercooler in and of itself isn't going to give you a ton of extra power, but you're maintaining power because the upgraded intercooler doesn't heat soak like the factory intercooler. The same concept applies with the upgraded cats/downpipes.

Now, with better flow from ported manifolds, upgrading cats/connecting pipes, theoretically the truck would be able to handle more fuel and get more power. Will we see that on the stock tune, not sure. Will we see that on the Whipple tune for those with Whipple superchargers, we'll know soon enough with @WMRaptor.

I have a whipple on my R but after how much I gained with the downpipes before hand throttle response wise we shall see. I will try to get some dragy before and after data on the ported manifolds.
Looking forward to seeing the results!

Crazy we've had these trucks for almost 3 years and no tuning.
It's an issue across multiple platforms. The level of encryption on the ECUs is getting pretty insane. The only way companies like Whipple have OBD2 tunes is because Ford has signed off on their ECU files allowing them to be flashed to the ECU.

This started in 2021, but the aftermarket found a way around it. They updated encryption in 2023 on the F-150 platform as well so the old way no longer works.

The R ECU is different from the EcoBoost ECU so you can't run a 21-22 ECU in an R like you can on a 2023 EcoBoost. The 24 ECU is different yet again.

Same thing started with the Super Duty in 2020 MY.

Eventually, the aftermarket finds a way. When the GM L5P motor launched in 2017, everyone thought it was locked down. Ultimately, HP Tuners figured it out for the 17-23 models. Things have changed yet again in 2024.

It's a never ending battle between the OEMs vs the aftermarket.

While emissions is a component as @Hard R mentioned, the other component is the manufacturers trying to lock consumers out of their own vehicles. Some have even gone so far as to claim that you do not even truly own your own vehicle, you've merely purchased a license to operate the OEM's vehicle. This is a huge thing in the agriculture community with John Deere as well.

This is one of the reasons why getting the Right to Repair Act properly codified into law is so important as it will force the OEMs to allow technicians and end users to have full access to the vehicle.

I have to get more runs in and see what it does. My RS3 was so consistent with how that car was and this is not lol.


Need brakes it scary over 120 trying to slow down.
Somewhere I read the best times were achieved by turning on the auto hold feature. Then just punching it.
