It's my understanding that it's so expensive now (vs getting older trucks tuned) because the ECM is encrypted, and not many people have figured out how to get around the encryption, so prices are high

The issue as already stated is encryption.  There are plenty of tuners out there, just none that have the know how and/or capital to crack G.M.'s encryption. They're may be some truth to cost analysis

Which is why they need to either bring back 4.10s, give it a competitive transmission, or release the rumored big block.    Or best of all, all 3 available in a truck!

I ran a Hypertech on my LLY Duramax with a tow tune in it. That truck had such an inadequate cooling system in it that it likely wouldnt take any extra HP/TQ. 

Gas is a different story, gains arent quite as easy. I am budgeting for an exhaust on my 2024 but thats about as far as I am going. I like the MBRP system

We ran banks stuff on our diesels. We had to beef up our transmissions to get full boost. My brothers diesel made short work of my trailblazer ss.

I'm using a Pulsar LT on my truck. I got it primarily for modifying tire size (speedo correction) and the ability to lower the TPMS threshold. Currently on 37s @ 40psi with perfect GPS matched speedo and no TPMS warnings so it does it's job. As a side benefit, it does that whole throttle response improvement act. Really makes the truck feel peppy and "normal" instead of sluggish delayed dog crap like stock. Helps a good bit with the famous GM 2>1 downshift clunk as the throttle isn't allowed to restrict down or whatever is happening.

 

It's no HP Tuners, but keep in mind HPT costs a fortune to apply, then you need to actually find a competent tuner to properly use it at another $600+. Then what are you really modifying for that almost $2,000 all in cost? Unless you are doing a camshaft change or SERIOUS engine work it's not worth the hassle for an intake/exhaust or whatever.

patiently waiting for someone to make one of these for a 2024 system.  Would love to adjust down my TPMS.  I don't like the empty ride when aired up above the TPMS threshold.

Can already adjust the TPMS on a 2024. I adjusted mine to 55psi front and rear and adjusted the tire pressures accordingly with an Autel TS508. I can't adjust the tire size, etc but no problem with the tire placard tire pressures.

Nice.  Need to find someone local to do that for me or find a shop that rents them.  Will ask the dealer but don't know if they'd be willing to do that.

Strange, i have about 65 in the rear and 60 in the front of my 24 3500 and no dash light. It has been that way all winter, and it gets cold hear, so that psi would fluctuate a lot without a problem. I havent reset or told it anything.

You shouldn't get warnings at those levels.  I think if you go below 60 in the rear, you'll see a warning.  I like to run 55 on all four corners when I'm not towing the camper.  Roads here in Arizona are great, but lots of places we camp, not so much.  Just about rattled my teeth out around San Diego and Orange County last week.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      While waiting for parts I have been working on installing the AC compressor, new accumulator, and orifice tube. Also changed out the high side ball valve (original). The orifice tube that was in there wasn't too bad. Slightly dirty, a little bit of junk, but not blocked. Glad I changed it out.   The accumulator, which should have been a 5 minute job, may have just burned $50. Put some PAG in it, wrote the date and mileage on the side, fresh o-rings and gooey'd up the threads and rings with Nylog. Got everything connected and snugged and was going to vacuum down the system, and....   My manifold gauge won't fit on the port. It's not an R12 service port. It LOOKS like an R134 service port but the diameter is a hair too large. There's a sticker on the accumulator that says it's designed to be used with R12 and R134a systems only. So it's not R1234yf. Even if I reduced the diameter slightly with a file, the shoulder on the port is too large so the quick-connect valve won't lock on. I'm stumped. It's going back, and 50/50 on if they'll give me a refund.   Also, I did a fuel pressure test.... Key on, the gauge spikes to about 60psi and quickly bleeds off, like 2psi per second. The fuel isn't going into the plenum, no smell, starts fine, so I'm guessing there's a bad check valve in the pump and the fuel is just draining back into the tank. oh, hell. But, it shouldn't be a problem, pump primes just fine and the truck starts right up. It just means I can't really ever use fuel pressure to verify a leak at the injector or intake.

      SERCICE ESC message?

      By No F-bdy Bs · Posted

      Got this yesterday out of nowhere. Truck is a 25',6.6 gasser with 8k miles.  Only semi anomaly is that the truck had been sitting, uncranked for 6 days. Elec Stability Control showed immediately upon cranking, not while driving. No drivability issues, just the message. Battery didn't seem to be weak when cranking over.  I drove it, killed it, let it sit a few hrs with no avail.  Truck is 100% stock. No damage.

      on-wheel cellphone control: 2026 1500 WT (2.7L 4WD std cab)

      This can be done.  It is not cheap and requires an instrument cluster swap with custom programming, new steering wheel with the controls on it, and a special jumper harness.   The cluster upgrade - 12.3” Digital Cluster Upgrade – 2022.5–2026 Silverado / Sierra (T1 Refresh Pickup) - WAMS   The wheel upgrade - Steering Wheel Upgrade Kit – 2022.5–2026 Silverado / Sierra (T1 Refresh Pickup) - WAMS   The column harness upgrade - 2019 - 2026 Silverado / Sierra: Steering Wheel LIN Bus Harness - Harness Dr. - DIY Done Right     The problem with doing all of this?  You pretty much can't have any programming done to your truck that involves the cluster ever again.  The dealer won't be able to program the cluster as GM's system will only pull data for the cluster the truck came with.  So it would be advised also to turn off over the air updates.   TLDR;  Should have bought an LT double cab?  You'd have a power seat, the wheel controls, the cluster, all things that you've been seeking in your various posts so far about your new WT regular cab.

      2026 TurboMax L3B 2.7L: AFM/DFM present/disablable? [2026 Silverado 1500WT: 4WD RC RB 2.7L]3GCNKAEK9TG345558

      Yes.  The 2.7 Turbomax has Active Fuel Management.  It is NOT the same as the V8s.  Totally different system.     Here is an article from GM when the 2.7 came out explaining the cylinder deactivation and the valve lift system.  Starts at the section called "SCS Valvetrain":   New Turbocharged 2.7L 4-Cylinder Engine Powers Full-Size Trucks – TechLink         This is an internet myth going around.  It was alleged that some 5.3s had this mystical 8th digit of the VIN as an "E" which somehow meant it had a new one year only 5.3 that didn't have DFM.  The writer of said article and the person that made the claim conveniently can't count because they posted the VIN.  The 8th digit was a "D" which meant its still the 5.3 with DFM.  The 9th digit of the VIN was an "E" and the 9th digit isn't the engine code.  At all.
