Not only did I do that with my 14 5.3. I can do that with my 02 Avalanche. Most any no weight over the rear tires pickup should be able to do that if so desired, with a little brake TQ. Nice show though. 👍

Thanks. No brake tq here! Just letting off the brake till it it 5 mph and nailing it. You can brake tq a 4 banger and make it spin. All I know is my 2020 Trail Boss with the 5.3 would only chirp the tires from a dead stop. If I was rolling like I was in the video...it would have never spun or even chirped them.

If you can take your 5.3 from a roll, nail it and break the tires loose through 1st and 2nd... I want to see it! Post up a video.

You appear to be one of those people that enjoys talking down to every option that isn't what you have. Nice. 1) a "chipped" 5.3 in 2018 alone gets you 385/413 HP/tq vs the stock 6.2 420/460 HP/tq.

The 5.3 has more than enough power and torque for my needs. I didn't even consider the 6.2 when making my purchase.

I never imagined that after asking if the benefits of one engine outweigh the other, that people would be yelling at each other about piezoelectric knock sensors.

My old 02 will roll through first easily. Being it’s a 4 speed auto not a 10 speed obviously not through second. But the same distance.  My 14 a six speed with E-85 and little TM would through second with a tune.

Going back to an older truck the throttle response was quite different than the newer trucks. Taking off without turning the tires was a re-learning experience. Especially with 373 gears.

Oh I know all about that! I still have my '06 silverado 5.3, 4.10 gears, cold air, MBRP exhaust with cats deleted and a Diablo tune with as tq management turned off, that I bought brand new in July of 2006. She goes for what she is....but it still won't light them up from a roll.

Every truck I owned since the 2000s could light them. Of course there’re tuned, exhaust, stock sized tires empty in the bed. Stock trucks without a tune the TC would intervene and shut them down with more than a chirp.

The 6.2 will break ‘em loose at 50+ MPH in the wet. Definitely took me off guard the first time that happened.

      Stabilitrak conversion to Z71

      By teamjnz · Posted

      Sounds like converting will be a bigger endeavor than I was thinking. This truck doesn't have 2Hi like the Suburban did. The Tahoe has 4Hi and 4Lo and a button to turn of traction control.   From what I understand the Stabilitrak uses open diff in the front and rear. When wheel speed is not the same the stabilitrak uses the ABS system to slowdown the spinning wheel(s) to transfer power to the slower non-spinning wheel(s). I thought the transfer case was open too. Being able to transfer power either more to front or rear depending on wheel spin. Maybe I miss understood some information with you saying and power transfer is 50-50. Thanks

      OCI, not when but why?

      By PunchT37 · Posted

      My brother has a 2007 Avalanche with afm 5.3. It`s got 176,000 miles. Runs like a clock. Never been apart. Co worker has a 2010 Tahoe with afm 5.3. 230,000 miles. Never been apart. Runs like a clock. So, even though cyl deac is a weak spot, they can go the distance.   BUT, these engines had the oil changed regularly, AND had 5w30 as spec. I wonder if they would have lasted this far on 0w20? I`ll bet not.

      I certainly could be wrong but I hear of pickups far newer than that 2007 cutoff which may not be going to the wrecker but are having engine work done and be that a reman engine or new engine or trying to repair the existing engine. Some of it would be design issues as per the cylinder deactivation system that GM has and one of those lifters wiping out the cam and the question of oil changes moving the needle or not on that whole mess, or in the case of Ford pickup engines that have the long timing chains and wearing them out and the roller followers and phasers and some of that certainly goes back to oil change intervals. But in those various cases the truck has all sorts of life left in it and so the unfortunate owner and may be original owner or used market owner that is pouring money into repairs so the truck is not seeing the salvage yard yet but damage is happening by infrequent oil changes. A friends son had bought a 2018 I think it is half ton GM and it had some sort of extended or used dealer warranty on it and of course the lifter issue bites and its rattling and so the dealer had to swallow the bill and was at least 7000.00 and I think they only replaced what they felt they had to replace so yeah, I can see that being a ticking time bomb in the not too distant future. Would frequent oil changes cure all these engineering "marvels", probably not but some engine designs have shown that they do much better if the oil is changed a lot more often then if the manufacturer service claims are followed. New trucks cost so much that there is an incentive to keep the existing truck on the road by repairing.

      Tranmission stays in Low

      get a good code reader, and find out what problems the truck has noticed by reading codes. cheap ones can only get basic engine codes, you may want to get one that can get codes from all the computers in your truck.

      This is sort of my point, salvage yards aren't overflowing with all these 'poorly' maintained trucks - excellent/good/servicable condition otherwise, salvaged only as a result of a bad engine from poor oil change regiment.    In my area, there are no 2007 to newer gm trucks/suvs in any salvage yards. A few are in the 'recyclers' with very obvious reasons for being there - wrecked.
