2022 RST 3.0 Duramax. A few mods. First pic is new at the dealership in January. Since then added the Havok side steps, tinted fronts, tinted front markers, boost auto all lights on mod, cargo light reverse mod, spotlight mod. Hard to tell but there is a 3" superlift w/ upper control arms and bilstein 5100 in the rear.....next up thinking about hyperdip the wheels and emblems in the brass monkey color.

I can deal with gas going up. Luckily my company provides a fuel card for me for my personal truck. 2022 rst duramax. Extremely lucky I know. But there is no way in hell I can deal with a Tequila shortage too!!!! (BTW, 1942 is one of my favorites)

If it's going to fail it's going to fail. It doesn't matter what device were programming is done to the engine. Guys who have done programming still have had failures. Enjoy what you have and make the best of it.

Yeah this mobile version of the forum is trash. I can certainly survive without tequila.

I don't have any recommendations for a product solution but I would suggest searching for Gail Banks engineering and their review on aftermarket differential covers.

I thought you were. And I was just giving you a little $h!t!! It's all good man!

You didn’t think gas would get this high this quick? What did you think was going to happen with the Alzheimer’s patient that is the President??

I bought a set of these years ago, work pretty well. You can cut the 2x10 to any length you need, so custom for your application.

If terrain allows it's easiest to just back the rear wheels into a ditch, lower the tailgate, then drive/push it right in level. If you do use ramps the grates are of no real consequence and provide a better foothold when loading stuff in the rain.

I just drive around in L7 (have an 8 speed) around town because I dislike the constant V4 / V8 switching. I always leave AFM enabled on highway trips. Had a Range device but disliked the GMC app always complaining it couldn't get data from my truck because a device was plugged into ODBII port. Also replaced stock muffler with a Magnaflow 12909 along with a AFE intake. Left the resonator after the muffler and do not experience annoying helicopter noise when in V4. I can tell its in v4 by the noise now when low speed driving but on highway its unnoticeable. Still nice and quiet on highway until above 50% throttle input then it sounds like a proper v8. Flow through muffler design and no annoying flapper squeak when cold. FYI - No noticeable mpg improvement with muffler and Cold Air Intake but its sounds a hell Ofa lot better. Supposed to give a few more HP and TQ as well. Black Bear Performance :: Intake Comparison Test Results - 2016 Direct Injection Models

Almost impossible, a lift that big would require to cut off and remove stock frontend frame brackets and cross members to install the 7-9 inch lift parts. Only way to do it is to get a doner truck and remove the brackets from that truck and a good welding person but even with that the frontend wont be right for it being square and specs from original measurements, going to be a big job. Best thing to do is sell it.

Another point.......you always hear about the few who've had lifter failures. You never hear about the tens of thousands who've had no issues at all. Statistically, you're highly unlikely to have a lifter failure. Just my 3 cents (inflation)

Almost 3 years, 34,000 miles and Truck has been great. Would buy the 6.2 again for sure.

Half of you people on this forum are insufferable. All you want to do is troll.

From the iink that Rmcgunner posted: This doesn’t work on all GM vehicles, but more so on the newer ones, especially those running the automaker’s new Global B electronic architecture which first debuted on the 2020 Cadillac CT5, followed by the 2020 Cadillac CT4, Chevy Corvette C8, 2021 Buick Envision, and the 2021 Chevy Tahoe, 2021 Suburban, 2021 GMC Yukon and 2021 Cadillac Escalade. Anyone got it to work on a pre-refresh T1 pickup? My understanding was Global B doesn't get to pickups until the 22.5 (22 refresh) 1500 pickups.

Disregard my previous post. A dealer in Texas posted pics on FB of a High Country they just got.

I remember where I was in 2008 when I filled up my '98 K1500 with a 30 gallon tank and learned that the pump shut off at $100.00.

Nearly 2-years and 20,500 miles and I contnue to be happy with my 6.2! No problems (other than the rear wondow leak..resolved), great peformance, reasonable mpg's and overall solid build, I'm well satisfied!

That pretty much sums it up. Also, if I can save $50 to $100 with virtually no effort, I’m in for that. I’m retired, I have plenty of time. Most of the time I drive near home in suburbia. Not much I’m willing to do different on those roads - typically 40 to 45mph speed limits. And no, I didn’t expect a truck to get good gas mileage, but I didn’t think gas would get this high this quick. I don’t drive enough to care, but it still hurts a bit going over $80 on a fill up. Still, I love my truck and have no plans to get rid of it anytime soon.

Who said anything about worrying about it? I do it as a game for mental stimulation while driving long trips. I can't speak for OP. If I cared that much about it, I'd have bought a prius.

And if I didn’t drive many miles I wouldn’t either. With fuel costs at $5.29, the 4.5 mpg difference I get between driving how I want and driving to maximize economy means a $75 a month difference. That’s not insignificant and would be stupid not to take advantage of.

That fake woodgrain jazz just screams "cheap".

Not that I have seen posted online or in person but it should be very very soon. There are lots of trucks, both GMC and Chevy listed as “In Transit” if you use the “view inventory” function on the respective websites.

Thank you... the old muffler was huge and way heavier too. Yes I do. Honestly haven't heard that much of a difference with it still active. Under 2.0k rpms the exhaust isn't that loud which is probably when DFM is active so I cant tell when its happening.

I have a 3.0 Duramax so not sure how much the below will relate to the 5.3 but it’s certainly possible, especially if you’re currently driving like that. I drive a 175 mile round trip for work 2-3 times a week. Driving however I felt like (included 80+mph in early mornings, “spirited” acceleration at times) got me an overall average of somewhere around 23.5 on that trip. I did it three days in a row last week and did all I could to get the best MPG. Driving at 60 on 55mph roads and 66-68 on 65 mph roads, the absolute minimum throttle input for the situation, and actually using auto start/stop. I ended up at 28.0 for the three days.

65 mph isn't it sir. We've all heard that doubling the velocity increases kinetic energy by a factor of four but that equation only considers the weight of the vehicle and the difference in speed. Below is the explanation that considers the entire resistive force. Not just weight but air resistance. Even minor reductions in AIR speed will pay fuel dividends. https://www.quora.com/When-you-double-the-horse-power-why-don’t-you-go-twice-as-fast#:~:text=Hence%2C in order to double,to reach 200 km%2Fh. The relationship between power and speed for land vehicles is not, unfortunately, linear. That is to say, that if you double the power you do not manage to double the speed. At any speed above somewhere around 40 km/h (25 mph) on a flat and smooth road, aerodynamic drag of the vehicle becomes the most important force that prevents the vehicle from going faster. For high speeds, let's say above 160 km/h (100 mph), aerodynamic drag of a typical car is so high that it can be considered the only force acting on a road vehicle, all the others being irrelevant compared to it (despite also all other friction forces having increased as speed has increased). So how does this force progress? With a fairly good approximation it can be considered proportional to the square power of speed. Doubling the speed from say, 100 to 200 km/h, will result in a 2x2=4 fold increase of aerodynamic drag force. A force applied to an object that moves against an opposing force, produces a mechanical work. In order for this work to be accomplished over a certain amount of time, a power is required. The shorter the time, the higher the power required. The relationship is linear: In order for the same quantity of mechanical work to be accomplished in half the time, power must be doubled. Mechanical work is force times distance; power is work divided by time. But distance over time equals speed, therefore power equals force times speed. This means that, if the opposing forces remain the same at all speeds, then speed is proportional to power and indeed, doubling the power will result in doubling the speed. This is what happens for example in lifts: if you double the power of the electric motor of the lift, it will (roughly) double its speed, since the force of gravity does not change with the speed of the lift. But the aerodynamic force that opposes the motion of a road vehicle is (approximately) proportional to the square power of the speed so, being power equal to force times speed, it must be proportional to the THIRD power of speed. Hence, in order to double the speed, the power of a land vehicle must be increased EIGHT TIMES! For example, if a land vehicle requires 20 horsepower to travel at 100 km/h, it will require 160 HP to reach 200 km/h. If you double the horsepower of a vehicle, all the rest being equal, its speed will increase of a mere 26%: again, if 20 HP were sufficient to reach a top speed of 100 km/h, 40 HP will propel the same vehicle at the mind boggling speed of 126 km/h.

My OEM camera, which is the same part number as my tailgate camera, was about $100 from one of the on line gm parts dealers. The cable from Pasternack was $36 shipped. The hard part was fabricating an enclosure. All the ones i found on line were huge. I used a pvc plumbing fitting. The tailgate camera angle is very close to 45 degrees down, so a 45 degree ell worked well.

I agree that a 10% improvement in the gas mileage of a vehicle is unrealistic. However, that assumes improvement from the rated mileage. Basically you’re saying if the factory spec for the truck is X, it will be hard to get a 10% improvement on that. However, I’m not suggesting that. I’m looking to improve compared to my typical highway driving style which is to get in the left lane and drive 80. Generally, trying to get where I’m going as fast as road conditions and such will allow. Doing 10% better that that shouldn’t be too difficult. Basically, I need to slow down and drive smoother. The question I was asking is at what speed would I find a sweet spot. Given one of the responses above, it sounds like 62mph. I doubt I’ll be able to do that, but I’ll start there and see if I can adjust to it. On a long, uncrowded stretch of two lane highway, I can probably pull it off. Going through a metropolitan area with three lanes and people driving crazy, I’ll have to revert to my typical driving. It will be an interesting experiment. How much gas mileage can I squeeze out of my truck without driving myself crazy. Trip is for two week later this month. I’ll definitely report back. I’m hoping I can hit something over 23mpg. That would be for the entire trip, not just something like a 50 mile stretch.

I wanted to post an update in the event that anyone else comes across this thread in the future with the same issue as me. I've now put over 600 miles on my truck since I replaced the HPFP, and the engine oil level hasn't moved at all on the dipstick since then. So I'd definitely call that a successful fix in this case. Thanks again to all who offered input with this issue!

Really? The government shorten leases on our land making it not profitable to drill. Took Alaska off the market. Shut down Keystone. Threatening other pipelines already flowing. Stopping or shorting leases offshore. Pushing electric vehicles before we’re ready to support them. It would be like having a pizza shop that’s popular and you want to expand. The government comes along saying your tomato field causes too much pollution. You can only have so much. The results you don’t expand and the price goes up. Same difference. I will not respond to you anymore on this subject, your delusional.

Obama proposed a ban on oil manipulation in the spring of 2012 in order to present an election deflection issue since gas prices were rising. This was done so as to provide his party with an argument to help the Dems in the midterms. It wasn’t any different when the GOP was saying they would repeal Obamacare. In fact between 2012 to 2016 they voted to repeal it on numerous occasions , but when they actually had a vote that counted , John McCain ( a Republican who had voted every time to repeal it) cast the deciding vote against it’s repeal. All this political theater is designed for the MIMS, which means the manipulation of the ignorant masses. One side blames the other side for being against there great legislative goals, and guess what, people actually buy into this nonsense and hence here we are. This is what we do know, gas prior to Biden taking office was under $2.00 a gallon, before the Ukrainian war it was up over $3.50 a gallon, and today in my state it is now over $4.00. Parties in power only want to take credit for good things and run away from the bad issues by blaming other people. So, whose to blame? I tend to look at whoever is the captain of the ship first, since they are the ones who are implementing there policy that they want to push forward. Sorry Joe, and by the way today is Monday, just in case you forgot what day of the week it was.

Love my 6.2 and get the same mileage as the 5.3 I had, just cost more to fill up as I run high test only. The lifter issues were on both the 5.3 and 6.2, I would hope they have it worked out by now as it was supposed to be only builds thru March 21. Lots of information here about it.

This sounds awesome. Really makes me want to ditch my bbq muffler. Do you have DFM still active? How does it sound when it drops cylinders?

Liking the 80's Alpine cassette deck inspired HVAC controls.

Yeah Im sure. Granted I dont know that I could have wired it up without popping loose the grill.

Lucky bastard!!! I envy you brother

Now that iam retired I drive less now so that helps my 2019 is 3yrs old this month and has 17,000 miles on it the wife has a 14 mile round trip to work but all in all these high gas prices is nothing but taking advantage of what's going on over there mean while the big oil company's will post there billion dollar profit report. Will the price of fuel go back down after this is over iam sure it will but never down to where it was and what gets me is when the price of oil goes up the price at the pump goes up instant now that fuel made still in the ground and in storage tanks was bought at the lower price per barrel but when the price of oil goes down it takes forever for the price of gas to go down. I could go political but iam not.

I’m sure my neighbors love me…. It was a lot louder in person…

Been busy the last few weeks. Went to North Carolina to pick up this 1969 Lincoln Continental. The 3.0 Duramax pulled great. Then did a 15k service with a new fuel filter. Then headed to Michigan which was Sally’s first time in snow. 3” and 17 degrees on our first day there. No def fluid problems or even real traction problems on the street tires. Not that I was doing any true off-roading, but didn’t tear up my dad’s yard either. Rolled 16k miles while getting 25.5 MPGs on the way back. Still loving this truck!

These trucks are not designed to charge an AGM battery, sure you can use them just fine, they just will not last long as they could have. Look up TP2, this is the code for a dual battery set up. Batteries draw down separately but are charged together. They ought to be the same. @intheburbs Bill has done a detailed installation how to on other forums that you can easily find for the generation after yours and I think he also had TP2 on his old GMT800 Suburban as well. He's a wealth of information to ask about such things.

Easy fix i had the same problem of coolant smell inside and out. out the side of the coolant tank drivers side is a pressure relief hose just extend it to the front or down under the truck I did mine at 12000 miles no smell since then 16000 on truck and of now

So I've been reading these forums for a few days now. The GM Trailer TPMS sensors are ridiculously over priced. Average $100 each Canadian or $70 each US. So I tested the sensors on my truck (2020 Sierra SLT) and found out they switched the sensors to 433Mhz. I thought if I try programming a blank sensor for a 2020 Sierra (433Mhz) it might read as trailer sensor. Sure enough it worked. So I got 3 more Autel MX 433/315 programmable sensors and programmed them for a 2020 Sierra. Took them out to the trailer and did the setup. Every thing works perfectly. Price for Autel MX 433/315 is $30 US each on Amazon. Any tire shop can program them for you if you don't have the tool. Be sure not to clone the ones on your truck instead do auto program. ID numbers have to be different. Other Brand 433Mhz programmable sensors should work too. But this is what I used and can confirm works.

factory z height is a measurement on level ground using a level and tape measure. You put the level on the knuckle bottom where the ball joint nut is. Place the level on the machine surface of the knuckle. Use the level and hold it level. Measure from the center of the lower control arm bolt at the frame of the truck, to the level. It should be between 5"-5.5". need to check both sides. Service adjustments allows .5" side to side.
