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.

      Tire psi

      By Chuck FB · Posted

      I just can't think of the exact term GM uses for that higher gvw package without looking at the website but basically sort of a trailering package and I imagine it may also have been created to skirt around the licensing fee differences between a3/4 and 1 ton that apply in some states although ironically I believe in some states its the reverse that a 1 ton is the cheaper truck to license over a 3/4 ton. It makes no difference here in Alberta but oddly enough a 1 ton through my insurance company is a bit cheaper to insure over a 3/4 ton as its based on the insurance statistics they generate.    For sure when ever you do have the chance to weigh your truck and to be fair, try to have the fuel tank full or nearly so rather than give yourself a false sense of the truck being lighter by having an almost empty tank.    In my other comment I was mentioning stock sized tires and partly in case someone was reading this and thinking they could lower their pressure down to what your aftermarket tires are able to do with your empty truck as that is a vastly different picture in the leeway you have to play with for running minimum pressures while remaining safe. I will say also that its easy to see from reactions of truck owners that may have been more used to owning a half ton in the past or a car and be it on a forum like this or in person etc that they get so wrapped up in that placard pressure sticker that they can't get their head wrapped around the fact that an HD truck due to how much it can carry can also vary the tire pressures drastically lower than those pressures ( typically more so for the rear axle on stock sized tires ) when empty vs some car that isn't made to carry much so the tire pressures can't be lowered since it needs almost that much pressure just to carry the empty car.    If I ever do find myself in the states with this truck, I will only be too happy to switch it over to the US measuring system as then I will understand all the dash readings. The only thing that is off for me slightly with US measurements is US miles per gallon as I grew up with the Imperial gallon and to this day up here anyway speak in Imperial miles per gallon ( I don't do that on this forum though as that would confuse everyone for no good reason ).

      Yes that's right, it's the upgrade that includes the overload spring and all that stuff.   Someday when I'm empty and going by a scale I'm going to stop in and get some weight readings.   Exactly  you should have the ability to change individual settings, in in Canada so I'm driving with kph but then I'm stuck with kpa when I want psi lol

      You must have that upgraded gvw package which is only available or at least was in 2025 with the diesel engine for the 3/4 ton and that gave the truck physically the larger 12.0 ring gear rear diff and the 3500 rear spring pack. There is a difference in what the diff housing looks like externally as one tell tale and also your truck should have the upper overload spring pack and the frame pads that the pack goes up against.    The pressure the tpms system kicks the alarm in on a stock setting truck, that is a good question and was just from what I recall but I doubt I made any notes on it as I knew for the rear that it was not at all what I was after regardless either. Being that you have a diesel and if running on stock tires the minimum pressure on an empty truck seems to be around 50 psi from hearing of those that have weighted the front axle but the rear axle is very similar in weight to a gas truck and again a near empty truck on the rear could go down to 35 pounds at minimum. However the weigh scale is the proper way to know for sure as a guide.    As to changing the readings on the dash from metric to the US measuring system, oh yes that is done easily but what I was attempting to explain was that I can't pick and choose items I want to have in US and those I still want in the metric system at the same time as its either all or none. For example lets say you drove into Canada and switched your dash over to metric so your speedometer read in km an hour, well then your reading kilopascals on your tpms readout and your wife looks over and says what the hell is that saying in the tpms screen and you say "darned if I know, I think its Chinese" !

      Some Assembly is Required

      By Chuck FB · Posted

      This is partly why I decided to have switched over to Amsoil SS as a way of hopefully preventing the buildup of the sludge/carbon on the pistons and clogging of the oil control rings and the carbon that would cause the compression rings to stick in their grooves as well as stay cleaner up top of the heads in the valve train in the first place, an oil that has tested better by third party testing over typical shelf oil and also doing my best to run relatively short OCI. However in saying that I don't think there is any way to easily prove the oil I was using prior allowed for a buildup at the OCI I was doing, nor in the other direction to make claims the Amsoil is keeping everything clean either. There really isn't a window into the engine is there to know anything for certain even if oil samples were taken for example that showed still healthy oil being dropped out of the oil pan other than engine tear downs that extensive and expensive testing of oils does to actually visually see what is really going on inside the engine. I wish there was some easy method of seeing what is going on but I don't happen to be aware of that if there is.

      My truck is a ¾ ton but my placard also says 80 for the rear tires, I think I might have the upgraded suspension to the 3500 series maybe.   I put my air down to 60 and the light was still on, and there was no way I was putting over 60 psi in the rear empty and not towing because I knew the actual number Toyo gave me and I didn't wanna ruin the center of my tires!   And you actually can change it in the settings from metric or is and it will show kph or mph then when you go into your tire settings it will be either psi or kpa, but it would be nice to just change it directly on the tire psi page
