    How much extra power can one make without unwanted wear?

    I did the complete AFM removal with bushed rockers my own tune CAI and Gibson exhaust and according to the internal torque sensor, I’m making 464hp and 507ftlbs. I hit the go pedal pretty hard and I have over 214,000 miles and no problems. FYI if you do the AFM delete you can reduce the TC...

    looking for service manuals - 2016 GMC Yukon XL 6.2

    I would be ever so grateful for a copy of the GM service manual. I have spent a lot of time tuning my 2015 Denali with HPTuners. I have made great improvements in the transmission shifting and starting on engine tweaks. I have 93 octane here in Michigan so I have added a bit of timing to the...

    *Update: Engine Down* Cam/lifter upgrades?

    I made it to 176k before a non-DOD lifter failed. I had them replace all lifters valve springs, seals and rebuild rocker arms with bushings. You want to replace the oil pump as the stock pump is designed for DOD which requires more flow. I had them replace the cam with a non-DOD stock spec cam...

    2018 Tahoe premier flowmaster 40 exhaust

    I put a Gibson stainless 3.5" on my Denali and disabled AFM. With that combination the sound is great and minimal noise at speed. I didn't loose any mileage at all. I get 20mpg at 83mph and 22+ at 70mph. I bought it through Summit for $470 for everything Cat back with a sweet 4" chrome tip...

    Normal ticking???!!

    I bet when your all done it will still make the same ticking noise. Buy a mechanics stethoscope from Harbor Freight. You will find the ticking is from a lifter. Could be a lifter or rocker arm issue, but that ticking is definitely valve train.

    2016 Yukon XL Needs New Transmission - Not Happy

    Seems like the 8L90 is the gift that keeps giving. It appears now I am having issues with the valve body and now when it's been driven for awhile on the freeway it revs up between shifts. I changed the fluid not to long ago and haven't put more than 30k between changes. I think there is a...

    Ticking noise coming from engine

    I bought a mechanics stethoscope from Harbor Freight, great investment. You can pinpoint noises precisely. I happened to remote start my Yukon when I was standing in front of it and noticed a ticking. I have it narrowed it down to #2 cylinder. I have disabled AFM, but I'm afraid I may need...

    Fresh oil change and catch can info

    I am at 176,000 miles and have been running Amsoil oil and filters since my free oil changes from the dealer ran out. I put a catch can in about 100k ago. I run my oil 10k between changes. I only get about a tablespoon of condensate every 10k. My oil is getting pretty dark, but I don't see...

    How common do the master window switches break? - SOLVED

    Picked up Covid on a business trip so it will be awhile. Plus I started a major brake project on my 03 Suburban. I'm replacing everything from the booster on down.

    How common do the master window switches break? - SOLVED

    I just ordered a new wiring harness from GMPartsgiant. They give you the ability to verify that the part will work with your vehicle by VIN#. On top of they had a great price, harness was $120 including tax and shipping. If you have a 2015 the part number is 84305359.

    How common do the master window switches break? - SOLVED

    Did you ever figure out your problem? I now have the same thing. After doing some online research I'm leaning towards getting a new door harness.

    Driver door controls don't work for remote windows or mirrors

    My seat memory switch quit working so I took it to the dealer to run a diagnostic. I had a free service coupon so it didn't cost me anything. They said I had a broken wire in the harness. I pulled the harness apart and sure enough the wire was broken clean through. I fixed that and put...

    whats the best floor mats/liners on the market right now for 2021 Tahoe?

    If you looking for quality rug mats I recommend Lloyd's. I have a set of Lloyd's in my 03 Suburban and after 17 years they are still in great shape. They're not cheap but they are the best. I have GM all weather mats and didn't like them, so I bought Weather Tech. I agree the rear cargo mat...

    2021 Tahoe High Country/93 octane or not?

    If the knock sensors kick in, your fuel economy will suffer. It's really cheaper to run premium.
