They just keep pushing the availability date back 2 week at a time. I wish they'd get them in stock already. Wanting to buy one.

I just installed the Pulsar LT on my 2021 Sierra AT4 6.2.  Five minutes to install the hardware.  10 minutes to program.  Very easy.  Speedo calibration for bigger tires worked perfectly when checked

To summarize the other thread... the motors affected were built before 3/4/2021. The TSB states the truck VIN build dates that are affected (with the aforementioned motors) are between 9/1/2020 &

For those who may still be interested, the site (ordered from rangetechnology) still says to allow 1-2 weeks due to demand.  However, mine came pretty fast.  Ordered late Tuesday, shipped Thursday, arrived Friday. Hardly sounds like a backlog, but maybe I just got lucky.

I purchased 2020 Chevy Trailboss 6.2L and I just hit over 6k miles and had take into shop bad lifters and bent rod.  Very disappointing.  I purchased the Pulsar LT today and when I get my truck back I plan to disable DFM and Auto/Stop Start.  I have noticed black res exhaust tail end cap or tips which indicates possible oil and gas issue also which could lead to carbon build up.  I hope turning off DFM will also resolve this and running all 8 cyl will burn properly and have cleaner exhaust. Think will also prolong life of engine (I hope) I’ve owned FORD , TOYOTA, NIssan but this is my first Chevy truck and having major engine issues 6k miles is concerning.

Welcome to the forum Eric.

Sorry to hear of your issue with the 6.2L. 

When you mentioned the bent "rod" are you speaking of a piston rod or a pushrod?

BTW, you'll really like the Pulsar LT. 👍

It’s pushrod.  Yeah everything I read says Pulsar must have to really get truck perform like it should.  I hope the new parts have resolved any manufacturing issue that causes failure in the first place.  My understanding trucks built certain time period has had this issue and have found these lifters didn’t meet spec and there were little to no quality control during COVID

I have a 2020 GMC Sierra 6.2L.  I always drive using L3 thru L10.  I’m pretty sure this keeps all 8 cylinders firing & it keeps auto start / stop dis-engaged.

 

Does anyone else do this, agree or disagree with this?

 

I have over 6K miles & no problems to date.

 

 Thanks

Worth every penny. 👍

Yes, November ? 2020 through March ?, 2021.  There is a topic on this forum specifically about the defective lifter issue.  A GM tech who works at the engine plant stated that engines built before and after those dates have the "good" lifters and lifter springs and should be fine.  But I still disabled DFM anyway with the Pulsar LT, even though my engine was built way after the defective date.  DFM causes way too much wear and tear on the lifters and pushrods with the constant activate/deactivating!  V8 all the time is the way to go.  Be sure to remove the device prior to any dealer service appointment.  Only takes a couple minutes  to install/uninstall.  👍

 

Here's the link to the defective Lifter thread... Lifter issue: TSB PIP5776E - published June 18 - 2019-2021 Engine, Driveline, & Exhaust - GM-Trucks.com

Getting ready to pull the trigger on one of these to replace my Range device on my 2020 RST. My truck sits during the week because I have a company truck, so I have to unplug the Range device every time the truck sits for several days to make sure the battery doesn't drain down.

 

I'm curious if anyone with the Pulsar LT has a truck that sits for several days at a time. If so, have you had any battery drain with it?

I've had my Edge Products Pulsar LT for 4+ months now and my truck can sit untouched for up to two weeks with no issues of any battery drain. 👍

Yes, I do the same thing, drive in L3 through L9 since I purchased the truck in March 2021. Also disable the auto stop/start every time I drive. So far, so good.

      If there are updates/fixes you want, you could pay to have the updates applied by the dealer.

      No Software Updates - Old Build

      By DaleB · Posted

      Hi all - my current truck is a 2022.5 1500 High Country 3.0. I bought the truck used last year. After doing some digging, I noticed that my truck's software is stuck on the original build from 2022. I have no available software updates. I talked to my dealer about this and they recommended not trying to force an update since the 36,000 mile warranty is expired. This is a big bummer since there have been many major releases since that have fixed small issues and improved speed/usability.   For reference, the current software build number is: full_gminfo37_gb-user 10 W158E-W164.4.2-QIH22B-563.3 158 release-keys Has anyone had a similar experience? Should I just forget about it and move on, or try a different dealer?

      Using zip ties but 2-3 they snap due to sharp edges. Just using a shoestring. Last longer. 🤣

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

      By Atlas · Posted

      I ordered the Snap On...waiting for it to come in later this week or early next week.   New front cover, new crank seal and new balancer are on. Water pump, pulley, fan, hoses, and plastics reinstalled. I can move forward knowing all my timing marks are dead on and the front engine is hopefully sealed better than it was. Take 2 with the water pump...trying high temp thread sealer on the lower bolts.   Rebuilt injector and new-new regulator is in, it looks like new. Top intake reassembled and all the bits are reconnected and snugged down.   Thinking about knock sensors again, I located both of mine and, there's your problem, Francis... The driver's side one is broke, plastic is bashed in, part of the wire is bare, and it appears to have been damaged like that for a long time. I saw the wire but didn't think anything of it. The knock sensor might not be my pulled timing issue, but it sure looks suspect. It must still be conducting, otherwise I'd expect a CEL. But perhaps with its sacred crystal inside exposed, jilted and dirty, maybe it's sending mixed signals. So I'm waiting for one of those and a new pigtail to come in. Pass side sensor looks good, except for the spark plug wire resting on it (!). The plug wires are healthy so it shouldn't be causing an issue, but I separated them and added zip ties to nearby looms to keep everything well apart.   So, I'm down to installing a knock sensor AND, oh, replacing the exhaust and cat. I actually think that's going to be fairly easy, it's all bolt-together, all new stuff from Walker is laid out on the shop floor ready to go. Hopefully have this thing on the road again for the weekend.   My luck? It will still be leaking oil, coolant, pulled timing, intermittent CEL for running rich, or it probably won't run at all -- because that's how this project has gone.   I've never worked on a vehicle so ...hurt? ...cursed? in my life. Everything has been effed with SO HARD, but I think...knock on wood...I've managed to undo all the backyard stuff and we're almost reset back to "just" an 80k mile, 30 year old Blazer.
