  1. Most of the time since I started driving I would trade for the next one because of HP increases. Every truck I did mods to increase power up to supercharging. All had tunes of some kind. Finally my 2014 was the one that I only tuned the transmission. I was finally satisfied. Of course I was 58. That may have had something to do with it.

  2. Here’s my 21 3.0 Duramax High Country, Sally. So far I’ve done: 2.5” front/1.5” rear Suspension Maxx level kit, Sumo Springs bump stops, S&B air intake, Chevy accessories hard tonneau cover, Sylvania LED reverse and tag light bulbs, 20% ceramic tint, and had the truck ceramic coated. Bought on July 3rd. Love her so far. Average 25 mpg on the highway at 10 over the posted limit and rides like a dream.

  4. Those motors are built the same however, they still have the DFM lifters, just no electronics to control them.

  6. To answer the question about the block heater, whether it was serious or not. The factory block heater doesn't work unless it's below 0 degrees Fahrenheit so that is kinda out of the mix for the majority of the time. Only the engine coolant would be warmed and the transmission fluid might warm up slightly quicker if you just jumped in drove off. I started my truck this morning as well and it like 15 degrees, let it run for 10 minutes and the transmission temp was 66 degrees. Drove my 4 miles to work and it got to 90-95 degrees with no thermostat. It acts just like my 2012 did without it. I didn't read much of the other stuff in this thread lol

  8. Well, did some more upgrades to the Work Truck package interior - this time to the dash. I was tired of the (to me) boring black surrounds and plain gunmetal radio surround. Upgraded to a few leather bits, chrome surrounds, and silver/chrome radio surround. Enjoy!

  12. They just came out with one... the Agilis has the 3PMSF rating.

  13. Anyone have any idea why Michelin doesn't have any 3PMSF rated tires that aren't a dedicated snow tire? Ive heard great things about the Michelin Defender LTX's, I'm just curious as to why. Maybe thats a question for another topic.

  14. I will most definitely demand them to fix it all. I dont want to hear "as intended" either. It wont fly. I have called higher ups before and Ill do it again if need be. Hopefully it will not come to that.

  16. “@M1ck3y” He can think what he wants. If he has a 6.2L or 5.3L come on over and I’ll prove that a 6.2L with exhaust and S&B CAI will take a stock 6.2L. Oh wait I’ve done it!! But I’ll do it again just for $hits and giggles and to prove a point! Plus, I also have a 5.3L in the family. My stepdad has a 2020 Sierra SLT 5.3L with 10 speed and it gets gapped considerably by my 6.2L, but his new 5.3L would gap my older 2016 and 2017 5.3L all day long. The K2s were “dogs” because of the lazy transmission programming in them. Now, will both of those increase even more with a tune….absolutely! Which is why I did it with my 2018 and will do it in the spring with my 2019. Don’t have time to let my truck sit for a week while ECU is sent out.

  17. All I know is my new 6.2L AT4 Sierra is a lot more spirited than my 5.3L Yukon. It would have to be a few car lengths at least in the 1/4 mile. It is also a few MPG less around town and that is me with an egg taped to the bottom of my foot when driving the truck.

  18. It isn't OCD to expect a flawless truck when you buy it new. If it isn't flawless, it REALLY isn't OCD to expect them to make it flawless stat. The whole point of buying new, versus used, is the flawless thing.

  19. I can't speak to deleting the magnetic ride system, and I have yet to replace the magnaride shocks on my Denali...but I replaced them on an XTS at 60K miles and the difference was night and day. The ride was not horrible yet on the old shocks, but the new shocks were well worth the money to replace. There's some discussion around Magnetic ride on GM vehicles and from what I've read & experienced is that they simply don't last much past 60K miles or so. Even if they don't fail immediately at that mileage, the ride quality dissipates quickly... If your current shock(s) have actually failed or frozen up, you will be amazed at the improvement new magnaride shocks will have. Considering you purchased the truck @ 83K, you probably have yet to experience the magnetic ride system to its fullest.

  21. I just switched from '16 Denali to '21 AT4. I expected the AT4 to ride worse than it does with it's shots and tires. Our other car is an Audi Q7 with 45 sidewall tires. AT4 arguably has a smoother ride. I suspect paint is thin, but this has been happening to various brands for years. I've hand clayed and waxed and didn't find any issues, but it is gray so good color for hiding stuff. Our dealer stopped their car wash routine during Covid. Thank goodness! I always order them to "no carwash!", but they occasionally forget. I have all the electrical noises. Fuel pump when you approach, noises under the dash when you turn it off. I don't think God even knows what all is going on in there. I've decided to ignore it. Radio has a weird boot up routine. Sometimes it starts out blaring before settling in to user preferences. No issues with glass yet. I noticed full size trucks were the worst category for all vehicles in Consumer Reports latest. I always cringe when the auto makers say "we've been making cars for 100+ years", because certainly they leave a little to be desired!!!

  23. I highly suggest you leave the cats. For one you'd need a custom tune to delete them and they act as really really good resonators to stop the horrible rasp and drone that can come without them. Leave the factory resonator for now and just do the muffler. To me it's better to do one thing at a time than 2 or 3 because you can actually find out if you like the sound before going to another step.

  24. Do they now? Here's a 1966 Volvo P1800 with over 3 million miles on it. https://www.hagerty.com/media/videos/the-world-record-3-million-mile-volvo-p1800-driven-the-next-big-thing/ Here's a 64 Mercury Comet with over 500K on it: https://www.autoweek.com/news/a1951956/1964-mercury-comet-half-million-miles-retiredwhat-next/ I have an Uncle with a 36 Ford C cab with a million on it and has never been rebuilt. Still oil tight and silent. What oil was that 36 Ford run on? That would be API SB oils until 1951 and SC till 1967. SAE 40W straight weight. Piston 'fit up' clearances are indeed tighter thanks to hypereutectic alloys. But running hot clearances are the same and so are rod a main bearings. .001" per inch of journal diameter and it's been that way for over 100 years. Drive it like you like it. Keep it tuned. Keep it full, changed, filtered, cool and use an OCI matched to the service and the oil your using and anything with a shell bearing will last longer than you want it to. Your read to many oil filter packages. This guy has a 225 slat six over a million miles without a rebuild. Go to 5:25 in this video.

  25. Wow, I never knew a topic such as this could become so divisive. For me, I'm just going to ask my service tech at the dealership. I have an extended warranty and I'm sure they don't want to pay out for potential early damage to the transmission. I'll report back ...

  27. I had the older Michelin LTX MS2's on my 2002 Silverado, rotated every 6k by Sam's club so they balanced them as well. They had 75k on them when I sold the truck and were just down to the wear bars. We have the Defenders on our 2016 Suburban and they are wearing well and still have a ton of tread on them with 40k miles on them. Same deal, rotate every 6k and keep an eye on pressure. Great tire all around IMO.

  30. I know this is late to the game, but I'm happy to provide some confirmation bias for you After my 275 55R20 Goodyear SRAs became drag slicks at 35k I put Michelin Defender LTXs on in the same size. Great tire, great traction, great treadwear, no noise, they handle hooligan driving well (think leadfoot launches and taking corners a little hot hahaha). I believe all Defenders are rated to 70k, I got 81k out of my first set with religious rotation and relatively close tire monitoring. I had a bad habit of running the pressures a tad high so the centers were at 1 or 2/32nds when I replaced them. My second set I got 67k out of them. Again, had a bad habit of running the pressures a tick high so the centers were wearing faster. The second set I replaced a bit earlier, i think at about 3/32nds just cause I had the tires on hand and I had a fairly long trip coming up (went from Casper WY to Las Vegas 7/4 to 7/9/21). Third set I'm rotating every 5k miles like I always do and am monitoring tire pressures much closer. Happy to report after 15k miles they are down to 11/32nds (from 12 new) and are even across the board. Michelin makes the best tires money can buy. Dad has run them on his Suburban, Escalade ESV, DeVille, first DTS, and his current DTS. They ride great, handle great, are quiet, and do great in inclement weather. I've run them on my DeVille and my Silverado and have equally high praise. Tried Goodyears once on my DeVille and they just are not as good of a tire. Same experience with my Silverado. The stock SRA Wranglers were ok but performance plummeted after 35k. Dad had Goodyears as OEM tires on his Escalade and had a tread separation at about 50K. Yours may be different cause of the different size but I think you will be very happy. Excellent choice!

  34. I take it that the converters are not balanced? I would think they are before any fluid is added. Drilling and adding a drain plug would put it out of balance. To me anything that rotates like that needs to be balanced, just like our tires and driveshaft.

  38. I've had her for a couple months now. 2020 Silverado 1500 LT. Only thing it came with from the dealer was window tint. Things I've added: 1) Rough Country side-steps 2) Pedal commander (that DBW latency is a pain in my ass) 3) Questionable tint all around, 50% on the windshield. 4) Magnaflow 3" single in/dual out cat-back 5) Chrome front end swap, less the fog lights. 6) LasFit turn signal LEDs 7) BulletLiner 8 ) 24" OEM replicas (24x10) on 33x12.5 RBP M/T's (mounted on 2" Supreme Suspension spacers) 9) 6" Rough Country lift (still sitting in the box, gonna wait til the 33's wear down then I'll buy 35's with more compatible wheels)
