So . . . is it installed?

From the previous version of this web site (generation 6) in response to everybody saying they are not important: "According to a good friend who is also a big name tuner says they're actually important. Over time he said that the car will use the rear o2 to help recalibrate the front o2...

All of these sites say the lack of a downstream sensor will mean that the engine mixture will be "rich," the safe mode.

I do not know anything about this, how it works, nothing. I am just posting what I find, which seems to indicate that the downstream sensors do play a role in air/fuel ratio. Upstream Sensor: The upstream O2S sensor is located in the exhaust downpipe before the catalytic convertor. It...

Looks like the exact same product without the Mustang logo and markup.

FAOSC?

The back seat and rear windows she is happy with, but that level of tint would be illegal in my state on the front door windows, so I am going to have to do them somewhat lighter to avoid encounters with the local constabulary. The ST is great with respect to performance. Handling is good...

It has been more than a year. Still like it? Did it hold up for a year or need replacement?

LOL Dark Horse and an Explorer ST in my driveway. My wife is asking for window tint on her front door windows for the ST.

I have a 2024 with no mods yet, so I am trying to pay close attention to what others do and the results.

This is the 2025? Were the headers on an otherwise stock engine, picking up 4 tenths, or boosted and picked up 4 tenths? Oh, and would you mind sharing what the larger resonator was? And was this installed with a goal of being quieter or for better flow or another purpose? Sorry for all of...

Hopefully Lund or somebody competent will be in the tuning business for the S650 at some point. That infinitely better processing probably leaves room for some excellent results.

Do the long defoulers affect the performance of the sensors in combatting sensor drift, as mentioned above in post 53?

Did it make a noticeable difference in sound? What about performance?

What does this mean?

But the "AUTO" button has three settings, right? I push it, it has three bars lit up, and the fan is high. I push it again, and now the fan slows to a medium setting with two bars illuminated, but, I push it again, and now it is one bar, and the fan is on a lower setting. What I am saying is...

I do not think you will regret it. It was some of the most fun I have ever had. Make sure to get a helmet (the new driver section will tell you what you need).

Does the Dark Horse do this? Even on long straights on the track shifting up through numerous gears at high rpm I did not notice this issue.

You'd know if it was HP because the sticky Trofeo RS tires would be tossing gravel all up under your fenderwells and if you drove more than 60mph in the rain you would be sideways in the road at speed.

What coolers does the Dark Horse have? I bought the Handling Package model.
