Does anyone know how to remove the governor on a 2023 CT5V? I plan on installing a JB4 tuner but from what I’ve read, that won’t help the top speed problem. What can I do that will not interfere with the JB4?
CT5V governor delete?

I took my 22’ 5BW auto to 172 mph & it was still pulling like a freight train…..on a back road I drive every day……amazing solid & in control but took a long time to slow down….

I have a 2023 CT5V Rear Wheel Drive, non-Blackwing; it is speed limited to 141mph. The warning message says 140mph, but I saw 141mph a coup of times. I have the optional 20 inch wheels.
I am disappointed that the car is limited, but it is a good looking car! Black on Black.
Interesting to know. Were you in track mode with any PTM enabled? I wonder if that would allow it to go faster.
Might be tied to the speed rating of the tires. Check the sidewall for the rating.
Michelin Pilot Sport 4S tires are rated Y, which is max speed of 186. Thats what came on my non-BW RWD with 20" tires...
I've only managed to get up to 120 so far... car felt the same as if I was doing 60... very impressed.
I agree 140 seems too slow for a sport luxury car marketed like the V. 155, i have found, is pretty standard. Something's up with your ride.
As of yesterday, the ECU and TCU encryption has not been broken by tuners yet. The opinion of my tuner (nationally well known, well respected and highly sought after), was "it's so complex, it might never be."
Somebody, at some point, somewhere will do it, but not yet. JB4 is only/best option right now. You lose some power and 'finesse'(tuning tactics) with a JB4, but they produce really well, across most platforms, on a healthy forced induction motor...especially if you already drive a monster. (BW.)
Speaking of tracks....
I saw a motox even t'other day. I have heard guys talk about and setting up their cars for it. I had visions of LeMans....Ford v Ferrari...etc. They set up comes in a big mall parking lot! WTH?! 🤣
My first Cadillac, so i dont know Caddie specifcs yet, but plenty of all season/3 season tires have high speed ratings. In terms of cost, there's no reason you shouldn't be able to spec one over the other. They are softer than summer/warm weather tires, though, so the sacrifice is lower mileage and, to some degree, performance.

Yeah, these engines run out of steam at the mid/higher end. That's not unusual these days as manufacturers push turbos with peak torque at lower and lower RPMs and HP curves that flatten out after 60 mph. Cadillac really should have made an honest V-sport version of the CT5 with either the 3.6L turbo from the old CTS V-Sport or (even better) the 3.6TT from the CT4-V Blackwing. Still, most of us are not going to experience the out-of-breath phenomenon unless we're on a track or just plain reckless.
Is your wife's car RWD or AWD? I find that the handling of my RWD V - especially on twisty roads with changing elevations - is close to perfect for a heavy four door sedan. Last fall, I was bombing around on just such roads near here and a friend in his modified VW GTI could not keep up in either the straights or the corners. Not bad considering the CT5-V's 1,000 pound disadvantage.
As l, maybe, stated prior, i just showed up (2 years ago) to the high horsepower sedan club. I'm still pretty starry eyed and amazed, in general. I find that the more capable the car (speed up, slow down), the 'more available' high speed roadways are. Ha Which is to say, if if you can get fast quick and get slow quick, you have more opportunities. I don't think anybody could argue a buck fifty is safe, but it's not that big of a deal, if you can go from posted limits to warp speed (say 80-150) quick....the world is your oytster. (Gotta use some restraint, though, and exercise a little judgement, as you can't account for random actions of people.)
Before my newest car (likely the last I'll buy for me), horsepower was just a number -actually, it literally is...math problem- and i didnt know what fast really was,all of my knowledge coming from Road and Track Magazine. No internet and a cars only purpose is conveyance is how i came up. 🤦
]Dating myself, but does anybody remember when the Mercedes AMG Hammer came out?I just remember the look and the top speed: 212mph...even more impressive 30, or so, years later. Wowzers.]
You are right, though, horsepower and speed is mostly just bragging rights to people that have, mostly, never experienced either. I look for every opportunity to drop numbers and beat down Mustangs and Challengers, especially. I have a usually heavy heavy foot, so my higher that most 'personal speed limit' for normal driving (adaptive cruise set to 90) and a sporty look and color pull in the meatheads who bought opted for 'cheap horsepower' with raging exhaust systems, thinking 'Scarlet' is easy prey. 😁 They, without fail, leave the engagement embarrassed, ashamed and questioning their life choices. 🤣 (396 Hemi? 5.0 GT? Camaro? Not enough! LOL)
For those not doing the math, I'm '52 going on 16'. We are who we are and mid-life crisis is a butch. 🤷♂️
Thanks for the interaction and tolerance of my addled ramblings, gents. Looks like I'm getting cocky and drinking a little too much of my own Kool Aid. So, please pardon me, if my posts are too familiar, at times. I'll catch you later.

You have to adjust the steering settings to get the best handling experience. That is to say, if you have the other settings adjusted as well. Personally, I think there are too many adjustments to cars these days. There should be two adjustments; all out performance and normal comfort!
You can certainly do that. Adjust the V Mode settings to your preferred max and the My Mode to your personal comfort. Each then available at the touch of a button.
No 'run the risk'...altering the factory tune will 100%, no doubt void the warranty. It's arguable, on the majority of the car, since the ECU is the primary 'brain' and the motor is the 'heart' (maintaining the analogy) that effects every component on the car. (The electronics integrated on these cars is insane. Conversely, if you replace/upgrade the sideview mirror on and the motor blows a turbo...the turbo is still covered.
My tac is, if i replace/upgrade a part (mod), I'm on the hook for anything that part effects.
Having/building a good relationship with the service manager is always beneficial. They get paid for warranty repairs and those guys are snakey and can find a way, if they want to. Using turbo as an example, as it could apply to you, if the warranty is denied you can purchase and replace it for WAY less anywhere else other than the dealer. So the dealership service department actually loses money in that case. It would benefit them to find a way to make it a warranty repair. $0 or another sale for $7-10k on the balance sheet. Which would you pick? 😉

Looks like this CT5 hit 140 MPH while trying to outrun the police. Not sure what motor it had but it is NOT a V or BW as it doesn't has the quad exhaust on it.
Definitely not a Blackwing.

(recognizing that I'm responding to a months-old post)
The summer 4S 19s on my RWD V are also ZR (94Y) rated - so, the governed speed (if it truly is governed) doesn't appear to have anything to do with the tires.
I've only come close to 100 mph so far but can say that this car is phenomenally stable at that speed.
