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.

      Injector update

      By iso221 · Posted

      Because single shot injectors are ancient and multi hole injectors provide smoother running engines and sharper throttle response due to the fuel being atomized better..the best lead I have is a 24lb blue top injector almost everything matches up but the injector will put out about 26lb/hr which is just outside the gm threshold.figured id ask here to see if there was an absolute answer

      Injector update

      By CamGTP · Posted

      Why is my question?   Any change in injectors requires a tune. Unless you are going back with the OEM part number or a newer part number of that same injector.   Any size difference or type difference like the EV6 style injectors all have different injector data for them. And there is no EV6 injector that matches the factory 25 lb/hr size that your truck comes with. I've been messing with these trucks and tuning them for a long time and what you trying to do doesn't exactly make sense to me.

      When a condition becomes a business model.    https://www.gm-trucks.com/gm-truck-suv-incentives-pricing-2026/   Zane posted this in "Latest Articles".    The honest bottom line   Truck buyers have spent three years assuming this is a temporary condition that will break once inventories normalize. GM just presented it to investors as a durable strategy, on a chart, as evidence of good management.   Inventory did normalize. GM is at 511,000 units and squarely inside its own 50 to 60 day target. The discounts still did not come back, because the low incentive number is the goal rather than a symptom of shortage.   Plan your purchase around that reality instead of waiting for it to change. Follow our ongoing GM News coverage for pricing and incentive changes as the next-generation trucks land.

      Winter Returned

      By Grumpy Bear · Posted

      Thought it was raining this morning when we woke. Nope. Dew point was over 80 F and humidity 98%. Zero visibility distance. Everything was 'sweating'. I've seen rain come out of clouds but never out of Pepper or the tree trunks.    Wicked storms just missed us sliding off to the east but by blocks. Heat index about 110 F with air temp in the 90's.    This is  our third wave this month of multiple days of this type of weather. And yet the grass is going dormant and the ground is cracking this side of the street and water up the the hood opposite. Just weird stuff going on.
