This weekend I helped my friend install a Jet Chip into his HD...well the Jet Chip is a ECM replacement or something so anyways you have to take the cover off the computer, brain box, and put this Jet Chip in between the Computer and the ECM Plug...now the cover doesn't hardly fit...I jammed in on the best I could with a set of C-Clamps but the plastic locks aren't in the holes to lock the cover on....I know this is hard to understand but if anyone out there has put a Jet Chip on the Silverado I was wondering if you even bothered putting the Dust Cover back on the computer...thanks or if you think  it will hurt anything..

On the previous generation C/K trucks, the PCM was on the driver's side fender exposed to everything.  So I wouldn't loose any sleep over it. The connectors are moisture sealing anyway.

What you need to do is get a 10lb hammer and motivate it on there.   :cheers:  Just kidding.

 

Does the truck runn fine other wise? its not the wrong chip?

 

If it runns, and its the right chip I'd check with Jet.

They sould be able to tell yea.

 

I hate saying this but, if all else fails, read the directions. :flag:

I had one of those Jet "power modules" (as they call it) on my 97 Tahoe.  It installed like he said.

 

I noticed firmer/crisper shifting, and it seemed to rev a little more before shifting.  performancewise I didn't make any documentation cause I never dyno'd or tracked it.  :cheers:

 

When I took it out this past July to turn the truck back in, I almost preferred it's stock settings better.  :flag:

Called Jet up its the right chip for his truck...I'm not worried a whole not about the elements hurting the brain boxs much..you should have see me finessing the cover on I broke the ribbing the center of the cover to get it to cover the connections and the only thing holding the cover on is the compression fit due to the tight fit on the computer housing...lol...I just wanted to double check...

 

I drove the truck before and after and I see loss of low end torque to be honest but I think it rev's a little faster and not to mention backs a better kick at about 60mph+ plus a real cool almost 4 barrel sound I heard it and I was like I miss my 750 and 1050 Holleys.. :(

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.

      2020 Trailboss 6.2 replacement

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      2020 Trailboss 6.2 replacement

      By 2017Z · Posted

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
