Must be a Trail Boss - AT4 thing - my AT4 at 98 as well (which was done off hwy of course).  Guess when they add 2" of lift they drop 10 mph!  My 2014 Raptor was limited at 106. 

Its not an AT4 thing its a tire thing. If you have 18” Duratracs that is prob why the 98 limit. My AT4 that came with factory 20” Bridgestones is limited at 112. 6.2/A10

Tires and driveshaft. Once a driveshaft comes out of balance at those speeds it will destruct with in seconds.

They do make one.   It requires voiding your warranty and spending a minimum of $1,900 to purchase a new unlocked computer from HP Tuners and the credits to tune it.   I doubt you'

Do you really want to take these high, loose un aerodynamic vehicles with truck tires with a significant forward weight bias at speeds higher than 100? 

No brains, no headaches...

I sincerely hope the is a 98 MPG speed limiter.  In my state a speed in excess of 100 mph is an automatic 3 month license suspension.

You better upgrade your brakes as well fellas that a lot of weight to stop suddenly if you have to.  Even though the brakes are good on the heavy trucks you may warp your discs if they get to hot during high speed stops.

My 2019 High Country shuts down at 112!  My 2018 Sierra SLT shut off at 98!  That was annoying. I tuned it and it shut off at 130! What tires were rated for. Had no problems with it at that speed. Now, I didn't stay at that speed for long. Just did it while proving a point to F-150's when they wanted to race! lol

bump for any news on programmer to unlock and delete speed limiter. Anything besides HP Tuner rip off

You know if that was all the HP Tuners solution was good for I would agree it is a rip off. However, it is good for far more then just the limiter which is why it is priced as it is along with the unlocked ecm.

 

It just so happens that is the only way to do what you want at this time so it isn’t financially viable solution to you for that purpose only.

 

Dont hold your breath on a basic plug in $300 programmer for these or future vehicles. Those days are over.

My truck is a T1. New body style 2019 High Country 6.2l and 10 speed. So the Autosync will do what I want with regards to changing the speed limiter?

      Ac not keeping up

      By Aimatdeer · Posted

      2024 l8t . Ac has never felt really cold even new. But lately it seems a little warmer. When it gets in the upper 80s and a little more humid it just does not keep up. And sometimes at idle it gets warm. My wife's 2008 envoy is better. My son's 2016 is colder. I have an apointment for a third try Monday the 29th at a third dealer to try and get cold ac before my warranty is out. The first two told me something about so many degrees under ambient temp blah blah blah seemed like they didn't want to mess with me. This was set at low. Max air fan speed high. 87 degrees and a little humid.   .

      OCI, not when but why?

      It isn’t all that bad in the world with purchasing power versus quality. My first car had just basic equipment. My oil choice was conventional oil. The life expectancy was around 100K miles. During that time you could expect to change all the accessories. Today with inflation you can buy the equivalent. It comes fully loaded with 4 doors. The life expectancy passes 100K miles replacing no accessories. If reaching that milestone is your goal you simply follow the recommended service intervals. If you want more miles simply do more maintenance. When in doubt you can check the internet or YouTube for information. The selling of any product hasn’t changed since the beginning of time. The power of the buyer has. The price of the product hasn’t changed much with inflation. The buying public wants more. Competition and the buying public has put the sellers in a box. The greed is on both sides. You can still get more for less. You just have to do with less. That used to be popular. The buying public has changed . It’s the sellers that are trying to keep up. As Grumpy tries to inform the readers in this case with maintenance. If you want more. More effort is required. That information wasn’t available this easily just a few years ago. I believe the public has more power. Getting information is easier.

      2023 DRW Wheel Liners

      By SFC Retired · Posted

      Gentlemen, I'm new to this forum. My question is, I thought I have read somewhere that the rear wheel liners for 2024- 2026 GMC Sierra HD3500 DRW can/will fit the 2023. I can't seem to find that information again and wondering if anybody has any knowledge if these will work or not with the 2023? Part# is 84892542. Thank you for any information. The GMC parts counter wasn't able to give my any definitive answer?

      Spacers aren’t safe anyway, so you’re better off just buying something else.

      OEM Trailer Hitch Receiver - Impact tightened by shop

      By carkhz316 · Posted

      Its because they have thread locking compound on them. I would bet money that they are actually reusable and not a literal TTY bolt because GM and most other OEMs don't trust techs and the end-user to apply thread locker properly in the same way they don't trust anyone to solder properly (and instead instructing crimps everywhere). Torque To Angle =/ Torque To Yield.   If you think dealerships or any technician replaces every 'discard' bolt in every procedure, I have a bridge to sell you.
