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.

      What have you done to your K2 today?

      By UrbanRage · Posted

      I have the same running boards on my truck and I do agree they are bulky. I also find myself stepping over them when getting in and out of the truck. Besides providing protection to the rocker panels, they aren't very useful.  I will be replacing them soon with the Amp Powersteps.

      Vehicle Payments

      By ChristopherDobson · Posted

      Monthly payment is only part of the equation. With today's prices and interest rates, I'd look at the total monthly cost: payment, insurance, registration, fuel, maintenance, and expected repairs. A vehicle that fits comfortably into your budget is usually the better choice than stretching for a higher trim. I've also kept my vehicles longer over the past few years. New cars have gotten expensive enough that driving one for 10+ years, while staying on top of maintenance, often ends up being the most cost-effective approach.

      OCI, not when but why?

      By Grumpy Bear · Posted

      10 Ford and Chevy engines proven to reach 300,000 miles   You may note a common 3K OCI on this list of gas motors. I skipped over the diesels. Dh'O.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.

      cam upgrade in CA

      By davester · Posted

      apparently CA smog is (or at least was)  checking that the vehicle is using the oem and/or a ca smog approved tune, so I expect you'll fail inspection doing it.
