The only listing Diablo has for 5th gen Ram is

PULSAR + T2 MX Kit 2019-2022 Ram 1500 5.7L Hemi​

for over a grand and it does not show speed limiter changes possible even at this price!
Pulsar is bs. Need a true unlocked pcm setup to do a proper tune. The pulsar is a piggyback tuner but all it does is truck the computer. The t2 is just to show live data.

It was mentioned before, and here it will be again.

Driveshafts and u-joints. They have rotational speed limits based on lengths, weights, angles, and quality of balancing. Upgrade these!

Although I must say, Throwing a driveshaft at 180km/h on the 401 would make for a great dashcam crash vid!

Here in Calgary we have the Deerfoot 500. Start your engines ladies, it’s go time!

And I can vouch for this first hand. Back in the very early '80's I had a '68 Charger that I got a wild hair late one night and decided to go fast on an interstate because no one was around. I got up to 130 mph and lifted my foot off the gas when my driveshaft snapped in half. It hit the floorboard so hard it bent my center console and threw my drink and dust in my eyes and everywhere. I had manual brakes and had both feet pushing the brakes as hard as I could while trying to see through watered eyes. The back end kept jumping up in the air when the back half of the driveshaft would try to catch on the joints in the concrete. Sparks were flying everywhere and it took forever it seemed like to get that car stopped. It was by the grace of God that I didn't get killed. I've done speeds like that 100's to 1000's of times and that's the only time something like that happened but it can happen. Slowed me down for a while but like everything else time heals but I will never forget that experience and hope it never happens again. Whenever I go speeds like that now that always comes to my mind and brings me back to what little bit of sanity I still have and makes me slow down!

Not disputing you, but i remember seeing max speed adj in AlphaODB. I was thinking that getting to 120, just enough to **** of my bro-in-law with him still strapped at 105

Oh yeah, GPS has it at 103 max

I tried it on my 2021 Rebel with AlfaODB. It didn't do anything. Maybe it's me...
Changed the setting, no error codes. But when I hit 170km, the Truck sort of dies, feels like engine shuts off, even eco light turns on.

105 MPH, LOL! That's about where the old 3 speed torqueflite would be when 2nd gear got ready to change to 3rd. Yes I bought my truck for performance, sue me! R/T stands for Road and Track, not ruts and trails. Really feels great to get in a little race and be passed by grandma's slant 6 Valiant that would probably do 120 eventually!

Yes, there are many ways to get into trouble at speed. I am an old drag racer and know about scatter shields, broken bell housings, busted rear stumps and dangling driveshafts. With that said, if I need to go 130 mph, say in an emergency situation, then there should be an override available for those who accept the risk.

Governor setting. Why the mention of updated drivelines etc. PPL also tend to forget the suspension , brakes and tires not made for those type of rotational speeds. Not know many PPL put Z rated tires on a truck. My County truck was a Ford F150 and they had that sucker governed at 99 mph. County bought cheap, and we ended having every truck in a shop to have beefed up brakes and rotors put on. The hubs were getting so hot they were melting the Ford Plastic hub caps. Always the cheapest bid, grrrrrrrr.

Ran a Crown Vic to 140, felt like a 72 LTD front end floating, white knuckle driving at the best.

Has anyone gotten the speed limiter raised successfully? I've read where some claim to use alpha to switch vehicle type to be able to get it raised then switching it back, I know there's a risk to doing so and really effing things up that way but some claim success, in just curious if anyone was successful any other way.
