So, are the GT active exhaust models and the Dark Horse going to be the same horsepower after tuning?

He beat me to it - ported intake manifold as well. BUT, the video highlights changes in horsepower from prior to the tune compared to after. This is actually development of the tune. He changes one thing at a time. He says in the video he made over 30 dyno runs as he changes various items...

Nope. Boss 429 ran in the 14s. Ecoboost still beats it in a drag race.

And, yeah, I bought the Dark Horse, but I am still impressed with the technological changes that have brought us so much horsepower. The Ecoboost produces more horsepower than the Chevrolet 350 did in 1969 and more than the Ford "HI-PO" 289 version in the 1969 GT 350. It also has more power...

The Ecoboost Mustang runs the quarter mile in the 13s and would have embarrassed a lot of the drivers at my high school in the early 80s with their supposedly "fast cars." An old Roadrunner with a big block 383 would have been running in the 14s. The hemi model would run in the 13s, but none...

It is a Steeda car at Palm Beach Dyno.

Why does the stock curve stop at 6,900 rpm?

Where do you get the bezel and boot? Fit and function well?

Wow, that looks way too easy. I am going to have to order one of the hoodies!

Big difference in the appearance and, especially, the weight of the first wheel and the linked wheel.

I really like the look of bronze wheels on the Mustang. You do not see that very often.

Will they stand up to a pothole?

Thank you to both of you for posting. I have a 2024 Dark Horse with handling package. My brakes are awesome, and I thought I would use the stock brake pads when the old ones needed to be changed. How do I figure out which of the two that you both posted are correct for my application (24 DH...

I pay $22 to the dealer. Like sdsteele2, I buy the oil and the filter on rockauto (cannot beat the price anywhere). For my wife's Explorer ST we also pay the dealer to rotate the tires, but I guess I can't really do that on my Dark Horse with the handling package.

Eager to see what happens now with pump gas, forced induction, headers, and tune.

Do you have a "how to" thread anywhere for this modification in an S650?

Not sure that it is possible to run out of inventory with a custom tune.

Roughly 4/10 of a second reduction in elapsed time and 4 miles per hour? Did you need spacers for the downstream sensors? No CEL?

Pushing down on the collar is not awkward?

I just noticed that fourth in the Muncie and seventh in the A10 are also the same, meaning that the rpm drop from third to fourth in the Muncie is the same as the rpm from from sixth to seventh in the A10. BUT second in the Muncie is 1.64, meaning there is a bigger rpm drop in the "close ratio"...
