Max speed limit from factory 105mph?

[GM convert]

Anyone else go fast? Mine shuts down at 105. Are there any tuners that can change this? Thanks.

I believe our trucks are governed to the max speed of our tires, makes sense.

I believe the recently released Diablosport tuners have the ability to change the speed limiter BUT you need to swap the whole PCM to an unlocked one. $$$$

I had a Superchips for my 03, and never needed a new PCM... it stored the factory values and made the changes... and it also uped the speedo governor from 112 to 145-150. I got it to spin the rollers on the dyno at 145. I have not started checking for my 19....

The new '19's are locked and can't just plug in a tuner like the older models. Not saying it won't be done in the future but currently you have to send your PCM/ECU in for reprogramming.

Mine caps at 104MPH, but my stock OEM tires are rated at 130MPH so I am guessing it is just what some engineer thought was acceptable.

Takes all the fun away, like the first hemis having 2 pcms, so no aftermarket touched them

2016+ are locked and require replacing. None of my other vehicles were like that so it did come as a shock to me.

I just went to the Superchips website, and see a tuner for the 2019 that would do limited things, but one was to Speed/Rev Limiter options... without a PCM, this is close to what I had for my 2003 Ram 5.7

From Superchips website. This is for the Flashcal options, (not the paq) price is 249.95, the flashpaq is 499.95 (includes PCM swap), DashPaq is $719.95 (includes PCM swap)

If you are a 2019 Ram 5.7L New Body truck owner who is looking for a device to help calibrate for your large aftermarket tires, read/clear trouble codes, adjust your speed limiter and more, then look no further. The Flashcal for Truck is a product designed to give features and calibration tools to truck owners at a great price. The days of clunky, outdated calibration tools are over. Flashcal has trucks covered and the market cornered with quality and pricing that can't be matched.

The speed governor is set that low to keep the driveshaft from coming apart. These long alum. 1pc driveshafts cannot handle being spun very fast, and will reach their critical speeds over 100+mph (especially if the truck has 3.92 gears).
