More Mods on the 2022 Stealth Performance - Hellwig & Livernoise Tune

[willalex09]

With the weather finally cooperating, I managed to tackle a couple of upgrades that significantly enhanced the driving experience of this truck.

Sway Bar Upgrade​

I replaced the factory front and rear sway bars with the Hellwig 7696 (front) and 7688 (rear). The difference was immediate and dramatic. Gone is the "boat-like" body roll I used to feel when cornering, and the steering wheel no longer jerks during hard acceleration onto highways. This is especially impressive considering the stock struts and shocks are already under added compression from the leveling kit pucks. Whether your truck is lifted or running a stock setup, I can't recommend this upgrade enough.

Livernois Performance Tune​

The sway bars were a precursor to the additional ponies via a performance tune from Livernois. Using their LPP631172 tuner, I sent in my stock tune, shared my list of modifications, and received two custom tunes within two days: a 93-octane performance tune and an 87-octane towing tune.

While I probably won’t use the towing tune, the 93-octane performance tune is outstanding. Previously, I kept the truck in sport mode almost all the time to get decent throttle response. Now, even in normal mode, the throttle response and power exceed what the factory sport mode offered. Switching to sport mode now transforms the truck into an entirely different beast.

Although it’s not a GT500, launching in sport mode is enough to spin the tires—and it can easily leave my buddy's 2024 F-150 Shelby Raptor in the dust (which he is beyond thrilled about lol). Beyond the fun factor, the tune noticeably improved the transmission's behavior. Gear shifts are smoother and more precise, with no more gear skipping or constant up/down shifts. The "clunky" feel I used to experience is completely gone. It also disabled the auto start/stop feature, which, in itself, is worth the cost of it all lol.

Final Thoughts​

Together, these two upgrades have completely transformed this truck. For about $1,500 total, the PPS (price per smile) evey time I drive this thing is well worth it.

Thanks for posting! Does the tune increase peak boost or just change the way it responds to the pedal?

That's a good question. It doesn't say in the list of items changed by the tune, but I'm going to ask them because I'm curious now lol. Let you know!

I'm running the same tune on my F150 EcoBoost. Prior to the tune, the factory boost gauge peaked at maybe 15-16lbs. Post-tune, it reaches 20lbs+ which is the limit of the boost gauge. This tune combined with using 4A for traction is awesome. I can't post the video here, but notice the boost gauge pinged at 20 psi:

Given some of the software bugs i've seen in these, I'm surprised exceeding didn't cause a blue-screen of the display, get that, blue as in the blue oval and a fault, lol.

11k miles on the truck since I installed the tune, and nothing has blown up yet. lol Not sure how accurate the PID's with the Torque app are, but I've seen it record boost up to 23 lbs using the app. I am an avid FDRS and FORScan user, and my truck is reporting no codes other than the PCM code losing comms with the active air dam since I took that crap out when I installed the Tremor skid plate on my truck. I'm very happy with it.

Maybe I am missing something, but if you have the SPP, you have the 440hp Raptor engine and sport tuned suspension (CCD). I have found this to be very adequate for everything! What does the extra tune do and is it really worth it with the SPP engine?

You’re absolutely right—one of the best aspects of free will is our ability to have diverse opinions, preferences, and priorities. While I personally find the stock Expedition (even the SPP trim) to feel "boaty" and somewhat underwhelming in terms of performance compared to its potential, I recognize that not everyone will share that perspective.

Having driven these vehicles for nearly 20 years—both in stock form and heavily modified—I can confidently say that a stock Expedition drives more like an Excursion. However, with a few well-chosen modifications, these trucks truly come into their own, offering the kind of performance and driving dynamics you’d expect from a capable SUV.

Of course, they’ll never match the performance of something like a Trackhawk, but it’s impressive how much you can improve handling, power, and responsiveness with the right upgrades. That said, it’s hard to fully understand the difference unless you’ve experienced both stock and modified versions firsthand.

In the end, the stock SPP is an excellent package and more than sufficient for most drivers. However, I’ve always been someone who wants my truck to perform at its best and be the absolute best version of itself.

You didn't answer the question though.

Actually if you read my original post as well as the subsequent comments, it is answered. If that isn't enough, a quick google of the tuner will tell you everything you want to know.

A little off subject matter: I have the Livernois tune on my 2018 explorer Platinum......it does make a difference. However, holding off on my 2021 expedition limited, due to warranty reasons

but if you have the SPP, you have the 440hp Raptor engine and sport tuned suspension (CCD)

The Stealth Performance Edition Package (304A) includes "Sport-Tuned Suspension", but not CCD. Sport tuned suspension and CCD are not the same thing.

"Sport Tuned Suspension and Continuous Controlled Damping (CCD)" is option 60R on Limiteds with 303A and 304A.

Mine specifically says CCD and sport tuned suspension. So what are you saying?

 

[bb37]

Limiteds with 304A include "sport tuned suspension". CCD is $1495 option on Limiteds with 304A.

What’s the performance gain with the tune? Maybe I read your attached image wrong but it looks like 430HP, which is 10 less than the stock SPP 440HP?

I guess some people can't spend 2 mins and google... My review contained all of my thoughts. If you want to know any more information about it, you can do a little research on this great thing called the internet...

I may be old fashioned, but I have been told many times..."RTFM"! In these modern times, it is SOO easy to get information about anything. Not so many years ago, before internet, we had libraries and consultants. And did much experimentation!

Exactly. Any information we could ever want is at our fingertips with a simple tap on our phone screen

Nice to find someone who has installed this Tuner as I'm almost out of warranty so starting on engine modifications.
I've ordered the AFE Momentum intake and now I am talking to the guys over at Livernois about the tuner ...I'm up in frozen Canada so likely doing an 87 and 91 for the winter months, and for 10 more bucks I'll throw a 93 on for fun.
My goal isnt to drag race around the city running 93. I highway commute 150km a day.
Goal is to obviously get some gains while increasing overall performance / fuel economy. I'm leaning towards upgrading the intercooler along with the tuner so the engine doesn't shit the bed working harder then needed.
Few questions for you, do you find your getting better fuel economy with the tune and did you upgrade your intercooler ?
Thanks!
