    2020 Suburban Premier w/ 250,000 miles. 11,500$

    NGK Plugs and factory AC Delco wires from Rockauto. It had GM plugs in it and Carfax said they were changed around 209k miles. The wires were suspect since they came apart when I pulled them out and I suspect they were old maybe original. Plugs on the other hand looked fine but I am trying to do...

    2020 Suburban Premier w/ 250,000 miles. 11,500$

    I got to 254k miles and decided it's time to swap the spark plugs. All was good for a few days, and out of nowhere I started getting CYL 7 misfire, and my mind immediately went to a lifter issue, but then I heard the spark arc across to something else, and went to check the plug wire, and sure...

    Might check out an '05 2500 suburban, what to look for?

    Nice! cant wait to see some more pics of that beast. I had no idea these things were so sought after. EPA lists them as getting 10mpg city and 15mpg hwy. If its Flex fuel I would run E85 in that thing all the time.

    What did you do to your 2015-2020 K2XX Tahoe/Yukon Today?

    Driven in michigan all of its life. Prior owner put about 55k miles a year, oil changes every 6 weeks at 6k miles. Motor is in perfect shape and so is the underside. I guess the daily airflow around the vehicle dried it up nicely and kept the salt from working its magic. Its sitting at 253k...

    FalkenWildPeak A/T3W

    I have 2 sets of the AT3W and they are great, quiet and do fantastic on back dirt roads, however on snow, especially if its packed they are useless. Nothing beats a snow tire on packed snow roads. Slushy roads are fine but anything that has a ice or sheen due to packed frozen snow and they may...

    Remove or Repair Air Suspension

    I used Magneride shocks from ebay and both sets front and rear were able to fix my OEM Magneride suspension and bring it back into OEM like ride quality. Not a single issue. Most people never re-calibrate the sensors and it throws a biast error. Without recalibrating the susepension may ride...

    Tips for maximizing fuel economy

    So side question for re-gearing, what all would need to be done? Escalade rear axle and maybe front diff swap? I have 2 Escalades at home both 3.42s, perhaps the parts can be swapped over, but they seem to be more peppy even off the line with the same 6L80 but both hold higher RPMs although...

    Died at 70mph on I-75

    Thats a huge bummer and not good having the family with you. This may be one of the only reasons that I chose to stay with the prior gen since they are not known to have these types of sudden failures and I think I am glad I went that route. Now the only thing you can do is wait to see what...

    Tips for maximizing fuel economy

    Mine has 3.08 gears and 5.3L it seems to do extremely well on highway at 75mph it’s right at 1700rpm and gets over 20mpg. On a few trips I’ve seen 23 and even 24mpg on V8 only mode. Bigger gears seem to make it run higher RPM which depending on the BSFC it may be a good thing. I can run in 5th...

    6.2 or 5.3?

    Have someone scan your engine cal with HP tuners. Your high pressure circuit may be disabled for AFM. If you delete that AFM you can enable it around 3000rpm and you will get about 60-65psi above 3k rpm. My L83 had it shut off. Oil piston squirters also work above 43psi so double benefits.

    2020 Suburban Premier w/ 250,000 miles. 11,500$

    For anyone interested in the factory engine cover from L87 Amazon sells genuine ones for about 77$. I wanted to hide some of the hoses and injector wiring and this was perfect. I have a 5.3L and it fits as if it was meant to have one from the factory.

    2020 Suburban Premier w/ 250,000 miles. 11,500$

    I think it comes down to use case, steady state driviving yes you can score some of those low 20s without problem. Try starting the truck with remote start, then start it again, to preheat the cabin, load kids, drive on back roads to destination, return home, leave truck idling to let the dog...

    New to Yukon world

    I wonder if the crank failures are related to the high pressure oil pump being factory disabled so it can play well with the AFM. I discovered in my 2020 the thing was shut off with a trigger point of 7000rpm something it will never see in real life, while police units have the cal set at...

    2020 Suburban Premier w/ 250,000 miles. 11,500$

    Couldnt wait and I swapped in the summer wheels to see how it will look! Cant wait for good weather. This thing gets a wash every day and its impossible ot keep it clean with all the mud on the roads around me.

    2020 Suburban Premier w/ 250,000 miles. 11,500$

    Found the flapper valve seized up, went to try and free it up and the flapper door must have fallen off and rattlign around in the muffler... solution, just throw a new 3" exhaust on it. Its a little bit loud but it quiets down when you are cruising. I may be adding a second muffler down the...

    Tips for maximizing fuel economy

    From a vehicle maintnenance stand point new air filter and injector cleaner with PEA should help bring back what eficiency was there and got lost due to reduced spray pattern and air flow. Cleaning the MAF is free. The other biggest thing you can do to see MPG increase is reducing rolling...

    What did you do to your 2015-2020 K2XX Tahoe/Yukon Today?

    No at highway speeds I am at around 1700rpm at 70mph and I have not heard it actually quiets down quite a bit. And once you get over 2000rpm it kinda wakes up and becomes throaty. Its a bit louder than I want it but there is always an option to upgrade the muffler for a different or longer one...

    Do yall use regular or mid grade gas in the 5.3?

    I run 87, but shortly after I got mine I installed the missing GM FLEX FUEL sensor, the wiring was there all I had to do was plug it in and copy the FF tables from a 2015 suburban into mine. Now it runs on any mix of 87 and E85. The beauty is at 30% flex fuel the equivalent octane is about 93...

    What did you do to your 2015-2020 K2XX Tahoe/Yukon Today?

    MBRP exhaust and new front struts installed today. Took me 2h at a rent a hoist place. Not bad. The exhaust is nice a bit loud but I like it. The suspension is now all refreshed.
