Gotta love how they put "V6 90deg" on a Ferrari-red label right below that 4-leaf clover.
Interesting intake plumbing route

So, what's up with the Alfa?
My Caddy V-Sport gets around 19 in town on premium unleaded, 30mpg highway. Tough to not want to put the 490HP to work, lol. Luckily the wife has a slightly less-spirited driving habit than I do despite her propensity for speeding everywhere she goes.
Unfortunately for me, the 6.0L turbo gave up the ghost yesterday in the Excursion so I get to wait on a new one to arrive in a few days and tackle that swap. Then it'll be back to turbine sounds, lol.I’m using that excuse next time

Slightly. KC Turbo Stage 1, but it comes with 3 custom tunes using my engine mods and ECU/Trans logic. It's got a bit higher flow than the stock Garrett but I still have stock injectors so that's really the only limiting factor. Turbo is capable of 500HP but mine stays south of 400HP as a daily. I did do one sacrilegious thing by opting for the 13-blade instead of the 10-blade (like my current turbo) to quiet down the Turbo whistle a bit. With a 4" exhaust and no cat it can be pretty shrill when next to concrete walls or buildings. Ford went to the 13-blade in mid-'04 to improve throttle response and quiet down the whistle a bit.You’re upgrading it, right?

Yeah I think so, too. With the larger than factory exhaust and no kitty, it amplifies the whistle as it is. I've never run any tunes on this 6.0L except a 40HP FICM tune (basically injector timing), but it doesn't increase boost pressure. The factory turbo would produce 29-30psi as it was, so I'm not inclined to push the limits too much with these "custom tunes", but the purchase of the turbo came with 3 free tuning maps (Eco Beast (90-120HP), Tow (30-50HP), Extreme (140-190HP)). Engine is studded/deleted with aftermarket steel (Kill Devil Diesel) o-ringed heads, but I don't want to push it on a daily driver.My 2003 F-350 had been upgraded to the 13-blade turbo at some point. I remember riding in 2003 6.0s with the 10-blade turbo when they were new, and yeah, that turbo was incredibly loud. Even as someone who loves the sound of a turbo, I found it obnoxiously loud. I think you'll be happier with the 13-blade. You can still hear the turbo and get that nice sound, but it's an appropriate volume.

Have you looked into the aftermarket on the Alfa Romeo? I'm sure you aren't inclined to mess with it yet (or at all), but I didn't know how much was available for it. Especially in the USA.
That license plate is genius level. Bravo.
Personally, I would throw a muffler on the 6.0 if it were mine. In fact, I did on mine.
I've got an AeroExhaust 5050XL on the RV. They make a 4" version (the 4040XL) that you could bolt in. However one thing the RV has that your Excursion doesn't have (I don't think) is using the turbo as an exhaust brake. That is exceedingly loud, like MU-2 level loud (not exaggerating) at very high pitch, and so it's good to get that muffled. The muffler is a see-through, very minimal restriction . . .
It does have a Magnaflow muffler on it so the previous owner was at least somewhat tasteful with the mods, but I don't know how effective it is as I have never heard a straight-piped version. To be honest the actual exhaust noise isn't that bad, especially inside the vehicle with windows up. It's just the turbo whistle itself that is audible inside, and REALLY audible with the windows down. Most of that noise seems to come from under the hood though, rather than out of the exhaust pipe. I at least have a few video clips of it prior to this new turbo, so I'll be able to get a fairly good comparison soon.
I have zero desire to do anything aftermarket…
Blink twice if you're under duress, lol.Ted, I think your account has been hacked. I don’t believe you would have typed that.
Remember this is my wife’s daily driver, it’s under warranty, and it’s a lot of fun just the way it is.
Oh yeah, and I have like 17 other projects to finish up.
So you're saying that your previous comment should have had the qualifier "at the moment" added to the end?
So far, the Alfa really has been a good car. By the time my wife gets home from her errands today, it will have right about at 3k miles on it. So far, knock on wood, we've had zero dealer visits. The only issue is that occasionally it will give us a "service parking brake" message (it has an electric parking brake like many modern cars), but it always seems to work just fine.
The UI of the infotainment system is very good and intuitive to me. It's simple and ergonomic to use. One of the things I really like is that it has Apple CarPlay AND built-in navigation. Going on a long trip and you don't want to be reliant on your phone (especially through areas of no signal)? No problem. Going local and just want directions for how to get from A to B that's easiest pulled on your phone? No problem.
Every time I drive it I say "This is just such a nice car to drive." Out of our fleet, it's the one I'd most want to take on a long trip if we were just looking for a car to drive somewhere. It's extremely comfortable, the steering and handling is fantastic, and of course it's fast and sounds good.
Sometimes the transmission doesn't do what I want it to, but that mostly comes down to the fact that it's an automatic and it can't predict everything you want 100% of the time. The different driving modes change the transmission and engine response as well as the suspension. Driving in "Dynamic" mode (basically sport mode) is generally what I do and it makes the exhaust louder/more aggressive. However when you do that, it won't shift into top gear unless you manually tell it to. Makes sense in some ways.
Fuel economy? Yeah, it's not very good. We get something around 18-18.5 on premium in our normal driving cycle. By today's standards that's really bad, and the 4-cylinder does way, way better. But keep in mind you don't buy a 505 HP SUV because you want to get good fuel economy. It still does better than the GL550 we had before, which got something in the 15-17 range, also on premium. We also specifically do not use the "Advanced Efficiency" mode with cylinder deactivation or auto start-stop in traffic (not a fan of either of those) and that probably does impact things some.
I do wish that it had cooled/vented seats like my Ram does, and on a luxury car with a sticker price of nearly $90k that seems a silly omission in today's market. However I haven't found myself missing it overall, even in our hot Kansas summer temps.
So in summary, I can't give anyone a reason not to buy one of these so far. It really is a fun car that we enjoy. How will it be 5-10 years down the road? Who knows, but there's nothing so far that's been an issue. If you're thinking about getting an Alfa, I'd say go for it. They're available, they're a great value (especially in today's market), you won't see too many others on the road, and they're a lot of fun.
Oh, and we got the license plate for it:

Why would it engage a parking brake while at stop lights/shift into neutral? That seems . . . odd.
I would presume it is due to an automated manual transmission, however, the specs call it an 8 speed automatic. I've owned a few cars with a dual clutch automated manual gearbox that will automatically hold brake pressure to keep it from rolling back on a slope since the car downshifts to neutral stopped. I suppose it could be considered a driver convenience/safety device on a light weight high torque vehicle such as the Stelvio QF.Why would it engage a parking brake while at stop lights/shift into neutral?
