If there has been stuff like this registered for other cars since August without being released, it makes me wonder how long we are going to actually end up waiting.

I am excited, increased HP, better throttle response, increased torque in the 2K RPM range and keep my warranty. I am all for it, this car desperately needs this IMO

Yup this is good news!

On the topic of headers, I have never dynoed my car but made quite a few trips to the track.

headers picked up OVER 4MPH on my 10r80 car in the quarter..
That’s a realistic 40rwhp plus in high rpm range.

dynos are just measuring tools, at the track, full WOT under load at speed, they picked up TON of HP…

hands down best bang for the buck next to a whipple kit.

The GT500 it's not a GT "with a supercharger".

Gee Dad, thanks for the education.

Hows the sound with headers and quiet mode? This is the only thing stopping me from Long Tube Headers.

I was just thinking bout a term I have not heard used recently

Vaporware

Why do I think we might be getting all worked up about something we are never going to see.

The software is set in stone because once it is CARB'd it can't be changed without a new submission and approval

The delivery system is either going to be a trip to the dealer or a hand held device that has already been developed and deployed

You'd think that Ford's Ford Performance division would want to recoup the costs of development, R&D and regulatory compliance ASAP rather than have it sit in a project folder somewhere where it is not recouping dime one.

The fact that someone stumbled across this info on a CARB website rather than an announcement by Ford that they had developed it and it would be available on XX/YY/ZZ has me wondering how committed they are to the performance tune being released.

I added a bigger resonator, now my car is quieter than stock in quiet mode, true 3” into factory 2.5 axle backs

Yep . 25 percent terriff applies.

lol why is that? Trump maybe introduces 20 or 25 % tariffs, but that applies for all IMPORTS - which means to car manufacturers who are selling the cars to the states, not the other way around. And besides, we are talking about a tuning modficiation, which probably will be a software and if it will distributed to Ford Europe as well, they have it in their system applied automatically.

Lots of naysayers here regarding potential price vs HP gains. Apparently I am the only person excited to be able to join the over 500 HP club without turning a bolt (it's just bragging rights, let's be honest). We don't have all the details about this tune yet or the cost. Might not be worth it, but will say I'm interested until proven otherwise that it is not worth the money.

I'm stoked about having over 500hp. Just hope 2025 is supported from the get go

That's only 20 hp extra, which is probably measured at the crank.

 

[93-Oct Mayne]

Because I want to feel more power. The car doesn't feel fast enough when you stomp on the gas. 400 plus horsepower in these heavy cars isn't that much.

The problem here is gearing on a non-pp car, I'm guessing

Non PP could still have a 3.55. Mine did. Not one Mustard could catch me.
