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.

      OCI, not when but why?

      By PunchT37 · Posted

      When I was there, most to all did not have an hour meter. They just did 5000 miles on regular vehicles and 3000 on police stuff. The modern oil change monitors should take into account engine hours, weather, etc. I don`t use the monitor on my stuff. I pull the stick, look at it, smell it, rub it between my fingers, etc. That`s my oci.   I have had many engines. Some bracket race. No problems doing things my way. I was in the mechanic business for 30 yrs or so. I still do things the old school way. Don`t care who laughs at me.

      I don't know how far back vehicles had hour meters, be it driver accessible or diag accessible but was wondering if there was any rule of thumb your shop came up with in regards to an hour limit on engine oil regardless of the miles on the oil.    I know with construction or farm equipment its almost always based on engine hours for maintenance scheduling as no other metric really applies other than a seasonal time limit that one self imposes on items like engine oil.

      I'm not sure what to say on that mess but I will say that is an odd thing for that mechanic to speculate on as per assuming its been run out of oil a few times as the odds of that engine having instead piled up with a complete seizure would be very high if such events had actually taken place. However there is nothing saying that the oil has ever been changed although once again, what filter was on that engine as that would tell part of the story if its possible to figure out if its a factory installed filter or not. Too many items unknown and a lot of speculation, but regardless of that its one fubared mess that is mind boggling to see for a vehicle that new and its hard to imagine how it ever made it that far in life looking at the top of the engine.    His scanners, I've watched him before here and there and I'd have to say if I recall correctly that some of his scanning equipment is one or two steps up from a child's Exo Sketch 😋

      I agree. That`s a LOT of sludge for 12,000 miles. I tossed that out here since this is an OCI thread. There`s tons of people here that do not post.   I used to work on a city fleet. That includes police cars and fire trucks. Lesson is, not to only use the odo for oci. A police car has a ton of hours on the engine for the miles it shows. And, not just idling, directing traffic. They beat on these things.   Course, since it is a Kia, they were gonna use the "100,000 mile warranty" for their OCI.😉

      Manufactuer's Defect - Paint Failure - Cherry Red High Country 2021 Suburban

      By AlVeron · Posted

      CLASS ACTION SUITS?  Does anyone know if there is already a class action suit for the paint - which was to have been fixed, changed in after the 2020 GM vehicles?  Does it look like this?    Just started 3 weeks ago - No help from GM as of yet - Dealer will not assist in speaking with GM on my behalf. Confirmed it is the paint they use along with the way the put it on that causes it to fail.  Clearly a Manufacturer's Defect.
