My 2011 silverado 5.3 seems to have a slight miss at idle, it is not a very smooth idle. I can even see the tach move slightly during idle.

it is alos sluggish on acceleration. If I'm going about 25 - 30 and I punch it like I'm going to pass someone it hesitates for about 1-2 seconds before it downshifts and gets going. I also have noticed a vibration or rough feeling when 20mph or higher. Not sure if it's a tire problem or drivetrain. Also during acceleration from a stop it seems to shift into 2 then 3 very quickly which makes it seem sluggish. Are these issues normal operation with the new trucks. My heavy 3/4 ton company van seems to to be more responsive than my Silverado.

I have to take it in for the transmission dipstick tube recall and will tell dealer my concerns then. I have always bought Chevrolet but am not very happy at all with this truck. I only have 7000 miles on it and keep it in the garage.

Hesitation is the GM "torque managment" kicking in. Basically a computer program to protect the powertrain.

 

Bad gas can also cause poor performance. So make sure your buying a good namebrand fuel each time. Chevron, etc. Try and find ethanol free stations too. It takes the truck's CPU a couple tanks of gas to "relearn" the different fuel qualities too....

 

The shifting could be normal if you have the new 6-spd auto. It is an always learning transmission. Google it for more info....

Fresh fuel maybe a can of seafoam will clean that up. Try putting it in 3rd instead of Drive. I run my 5.3 company truck like that it gives it more snap in acceleration.

I placed that order for the autocal it was $549. I haven't received any confirmatin of shipment and they don't reply to

my emails. Is this how they run the business ? I know that I will have to get the tune by email but so far that is

not off to a good start. I don't want to wait for days to get emails responded to.

I am begining to second guess my order. Any thoughts on this ?

Well, you did just place the order a couple of days ago, on a weekend.

 

Also, Justin often travels on weekends to do in-person tuning. I'm not sure if he did this weekend or not, but it happens often. BBP is a reputable and honest company, but they are a small company, and that's why they can keep their costs down like they do. They're also extremely popular. Being small and being popular also means that sometimes it may take a day or two to return an email or call. I'd suggest just hanging tight a little longer - it'll be very worth it.

Justin was on a tuning trip this past weekend, but chances are, your AutoCal went out yesterday. Your PayPal receipt is your proof of purchase, we usually ship AutoCals out within 2-3 business days (more times than not, the next day).

 

We receive hundreds of emails a day, and are typically 2 business days behind due to the sheer volume. Folks will notice an increase in response time due to sending multiple emails. Our server shows us emails in the order received, based on the most recent received. Multiple emails merely push folks further down in the queue.

Should have gone for an in-person tune this weekend and still get a Autocal.

 

Be patient

      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."

      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.

      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.

      AFM Disabler Question

      Melling I believe is/was the OEM on the lifters who explored this problem some years ago. The white paper they generated on the topic indicated two items of note when I read it. 1.) They only fail on the switch. Prevent the switch, prevent the failure. 2.) The majority fail due to deposits messing up the timing of that switch. Anyway that's what I got from it.    Mine have always been active, 195K+ now, and my oil maintenance is surgically clean.    Of course this assumes good parts. That is no heat treat issue or machining flaws. I get comfortable that these issues are in the rearview mirror by about 30K. IMHO naturally.
