Any news on a programmer that will unlock and change the 106 mph speed limiter for the 2019-2020 6.2l silverados?  Do not want to change the computer out, just unlock to change the speed limiter.

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'

Nope, but mine goes to 113 and stops.

I have though that the speed limiter setting is a safety concern and set based upon the performance specs of the stock tires.

My tires are 118 mph rated and there is a good safety factor on top of that. I would expect these T rated Bridgestones to be good for at least 125-130 regardless of what the mfg states. They have to protect themselves.

I doubt you're going to spend that kind of cash just to go over 106mph every now and then.

My 2019 Carbon Pro AT4 kicks in at 98 mph - very annoying!  Well below the tire rating - but I guess they dock you another 8 mph for the 2" lift!

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?

What gear? 6 or 7? I think mine boggs at 106 is about 6th and I still have 4 more gears to go. Sucks

 

I have no idea, it was still climbing, I hit 113 when the limiter kicked in once before.

Damn I had no idea you guys were over 100. I'm governed to 98.

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.

      Cold start Miss, oil in cylinder

      By Keith179 · Posted

      I’m out of ideas on this truck. 2020 Silverado 1500. 5.3 135,000 miles. Has a p0308 and p050d codes. Smokes From exhaust when cold. Compression test passed. New plugs, wires and coil on cyl 8. Same issue. New coil on 8, no change. Replaced injectors, no change. Bore scope showed oil pooled on the piston after sitting overnight. Pulled head and had machine shop check it out. No cracks. Stem seals looked good, replaced anyways. He also ground valve seats. Put it all back together and still have the same issue. Bore scope shows oil on the piston again. Leaning towards maybe a cracked ring but unsure. Cylinder looked good when the head was off, no scoring or scratches. Any ideas on what else I should look for?  Appreciate the help

      2021 Silverado 2.7L – N232395310 – Can someone with GM dealer access check my VIN?

      By HeronLeal · Posted

      Just want to make sure it is covered by Special Coverage N232395310 Evaporative Emission Purge Pump 2021 Silverado 1500 Custom 2.7L L3B ~100k miles I'm getting DTCs P146B and P146F. VIN 3GCPWBEK2MGxxxxxx   I spoke to a person that works at GM and he said it is not covered after checking my VIN.   Is there anyone here who currently works for a GM/Chevrolet dealership and has access to GM Global Warranty Management / Investigate Vehicle History who could explain how the VIN eligibility is determined?   thank you

      Tire psi

      By jgaudet99 · Posted

      Thanks for all that information, I might purchase one and see if it will work for me, if not they may let me return it! Yes for sure the tires are definitely within limit for my truck empty, and when I do tow I'll definitely make sure to raise the rear psi for the amount of weight that's going to be on it.

      Tire psi

      By Chuck FB · Posted

      Yes exactly, more and more these days people/companies are afraid of liability issues so its easier just to say no rather than risk putting their neck on the line.    I will say with the Autel unit or when I used it last year on my truck, it wasn't like I could choose the 2025 model year or even the 2024 model year as that option was not there to manipulate the placard pressures but had to go back to 2023 or there abouts and then it showed up as an option, odd but that was how the software was then and I can't say one way or the other now as they throw out updates every so often. I still would talk to your tire dealer though to start with and they may do it for nothing but also they may have a comment on a better unit to purchase. All I know is that one of the large tire shops in my area happens to use these Autel units for their use and set them up to use the wifi and all of that jazz for constant updating because each tire tech has one handed to them by the shop but I just plugged it into my laptop to update it and yes if one is bought it has to be registered so you can get the link to do updates and then the unit has to be updated before its even used. I am not at all techy so it took me a bit but anyway just a heads up for anything you buy, most likely it will need to be connected to a computer to access the internet to have it updated to the latest software version before you can put it to use.   If your truck is near empty, those tire pressures you listed are a very safe upper range pressures to carry the weight, both the front and rear as I know they could be run lower yet with an empty truck. And if its a trailer and not some motorcycle your going to strap onto the front of your truck on a rack, you shouldn't have a need to inflate your front tires if your at 55 front already, its the rear ones that would need more air if you have much hitch weight.

      Tire psi

      By jgaudet99 · Posted

      Thank you, I'll check that Autel scanner out and see if it will work for me! Ya I can see GM's point of view if they lower the psi set value for someone and the person sell's the truck and the new owner puts the factory tires back on then their could be liability issues cause the psi warning light wasn't coming on when the tires were under inflated for towing their load and then it might be able to be traced back to GM lowering it.
