I’m sorry I worded this poorly,

 

I installed the gm Cai MYSELF, then brought the truck over to the dealership for a RE-TUNE.

 

the dealership is trying to charge me for the re-tune

Your tech friend is fully wrong in this case. The calibration that GM updates with the GM CAI modifies and changes the MAF scale and corrects the AFR for when the truck is in Open Loop during WOT. The

Ouuu this one adds visual appeal to the engine bay with a performance oriented style. You spent 700.00 for something that looks like a performance mod? Ouch! Sent from my SM-N975U using Tapatalk

I have the GM CAI on my 6.2.  I'm going to get this filter from AMSOIL and see how it fits.  If so then this will be my replacement filter.  The price listed is the retail price.  Anyone wanting to ge

This is what I’m saying, I installed it myself and brought to dealership for re-tune, should be covered right ? 

Yes, as long as you have the code for them that came with the CAI,  They will use that to update the computer and charge GM.

I installed mine also.  I took the truck in yesterday.  Took the dealer about an hour because they were busy.  Showed them my paperwork from where I bought it and no charge, no problems.  The billing number they use is on your paperwork.  I really did not notice any improved throttle response but the idle is smoother.  FYI the speed limiter on the 6.2L is set at 112MPH, have to find a way around that.  No tuners out there yet.

Please purchase a custom driveshaft first. They are the weak-link and the reason for the speed limiter, that and OEM tire ratings. Many K2 guys found this out the hard way.

Interesting, I did not know that and did not have any issues with the aluminum driveshaft on my 2015 K2.  Most of the speed limiter are set due to tire speed rating plus a truck really has no business going that fast.  With that said, it was pulling real hard until the rev limiter cut the engine down. I love this new 6.2L engine.

You speed is limited to the tires that shipped with the truck.  My 6.2 is limited to 98 (TB with duratracs).

Right, but they must apply some unknown GM formula also, to give themselves a big pad on prospective warranty claims.  My last new Z71 was governed to 96mph which was 86% of the capability of it's "S" (112mph) rated Dueler A/T's.

If you hit the speed limiter at wide open throttle it'll throw you forward in your seat because of the sudden stop in acceleration. Been there, done that.

I don't know of anything other than the tire rating.  The duratracs (according to goodyear website) that come on the TB/AT4 have a speed rating of 99.

      I had an 88 K1500 with a 5.7 that had those symptoms, I know totally different, it ended up being the ECM. Once you get the fuel system fixed if it still runs lousy you may want to investigate that. it didn't set any codes, stalled ,ran rough at times etc

      Congratulations Isttype, on your gmc. Really like my 2024 2500hd sle doublecab now with 85,500 miles.  I checked the oil today at 4800 miles since last oil change and barely reading on the stick.  I don't care if GM says it's Acceptable adding a quart every 2000 miles because that is 100% BS, It is not a 1966 Harley Shovelhead! Sounds like it's setting up a future failure like I had with my 1500 6.2l. Other than oil consumption problems, I really like the 6.6l gas and 10 speed is really nice.  Towed a light 4000 pound trailer last week and averaged 14 mpg.  I was pretty impressive that a 7300 pound gas truck did 14mpg towing, Later-

      Long Term Cold Cycle Limited Testing   Back to the 1990's and XOM's million mile test. Since then there have been others and there will be more. Schaeffer's, AMSOIL to name two. Of these Schaeffer's is the stand alone which I will explain in a bit later.    http://papers.sae.org/600190/:   http://papers.sae.org/850215/:   Up to 75% of  engine wear occurs on cold starts. These two links (above) provide the technical reasons for engine wear. In a nut shell, and by a large margin, cylinder wear is what takes out most motors and even with a pre-oiling system that part of the engine is dry enough on cold starts and cold warm up to pierce Stribeck.   So when you put a motor, or a car, on a dyno for a million miles stopping only for oil changes, (yes fuel is uninterrupted) or break down maintenance, you are depriving the test of the most important part of it's wear cycle. Yes a million is then a pretty easy walk even for a mineral oil under those conditions.    How about cleanliness during the long test cycles? Same thing. Varnishes that stick rings and insulate parts are laid down by repetitive 'heat cycles'. It's the cool down the precipitates the varnishes. These long runs also hinder acidic attack caused by cold start richness and less than optimal cold start ring sealing. They hinder water formation and enhance breathing of the crankcase; the petri dish of acid formation, the first step in sludge formation, amalgamation and precipitation. These motors are also monitored and controlled for water and oil temperatures to within the "normal operating range".      https://www.swri.org/sites/default/files/sequence-iiih-test.pdf Note the test sequence in some boutique oils literature for testing, API IIIH, is not the standard used for the ILSAC G7 testing. Does that mean it is irrelevant? No, not as used. As used as a 'visual guide' it makes it's point. The G7 weighted piston deposit minimum is lower.      Back to Schaeffer's. That was a cyclical test of an engine in fleet service and not a dyno mule and if you saw the video it was not mirror clean but wear was low.    There are oils like BioSyn and other 'Renewable" source oils that taught cleanliness and have proven themselves in fleet testing. Havoline an other example.    The newest ILSAC G-7 test prioritize cleanliness, LSPI mitigation and fuel economy OVER WEAR. In comparison Porsche C30 Specification Verses ILSAC G-7 Specification below:      Some will balk that this graph isn't apples to apples and I will challenge that in that this graph represent the SPECIFICATION and not the any One Oil Performance.   It is absolutely possible to minimize wear, maximize cleanliness and mitigate LSPI etc., It just isn't cheap and currently I see none that are not walking toward profit over performance.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      I don't think you will need a split, separate product, etc., the OBD port should be able to deliver everything you need. Since your device would be plugged into it all the time, it wouldn't miss anything.    Hardware in this case will be the easiest part of your project - ELM 327 devices will already deliver all the data you need. Reporting/software is where your advantage/marketability is.
