    Feels like I am driving over rumble strips.

    So I still have my Denali for one more month and am using it for odd and end jobs. The thing I noticed over the post several months, which is getting predominantly worse, is it feels like I am driving over rumble strips. Like the ones they have in the middle of the road to keep you from...

    Tires, Black Bear tuner, Volant air intake

    Turning my 2015i in off of lease and have some items for sale. Tuner and intake are both around 1 year old. Tires were installed earlier this year and still have the nubs and yellow stripes on tread. Tuner will need to be sent back to BB for your vehicle. I believe it will hold 5 or 6 tunes...

    Coming off lease- what would you do?

    I’m coming off lease this October. I’ve enjoyed the Denali. I’ve actually recently had it ceramic coated, Blackbear tune, new tires, exhaust, intake, and vinyl wrapped the chrome. I’ve done all this with the intentions to purchase the truck. The residual is $42k. Nada has a retail value of...

    Valet mode

    I recently took the Denali in for an oil change. I placed it in valet mode because I keep valuables in the console. When it was finished I started the truck and it was out of valet mode. How did this occur? They did nothing else to the truck other than oil change. If there is a way for the...

    Anyone's paint chipping off?

    The bottom quarter panels of my Denali look like they have been hit with a sandblaster. I can understand if I had driven it for 75k highway miles. However I only have 33k miles and this began almost months after owning it. What is the paint warranty on these trucks and is there any point to...

    Anyone running 285/45-22 Yokohama Geolander AT's?

    I upgraded to Michelin LTX tires after about 10k on the OE tires which was an incredible improvement. However now the LTX's are about shot with less than 20k miles on them. Evidently this is the #1 complaint with this tire! What a waste of money. So I am looking to upgrade to something with a...

    iPhone X and text messages

    My new X is linking with my head unit. I can place calls, listen to music, receive calls. However when I receive a text message my head unit no longer receives the message. Everything appears to be set up correctly. Is this just another iPhone conflict? Sent from my iPad using Tapatalk

    Question for those of you that upgraded your fog lights to LED.

    Which way did you angle them? I was thinking I would aim the LED's up and downward. However perhaps side by side gives better coverage for a driving light since I want a wide sweep. It's really a pain to access this area so I am hoping to get it right the first time. This is what I purchased...

    Is there an easy way to get to the fog lights?

    I want to change the bulbs to a 5K and the owners manual makes it appear much easier to do so than actuality. Laying on my back under the truck I can't see how I can get to the bulbs without removing wheel liners or several pieces of trim hardware. There has to be an easier way.

    '15 Denali 6.2l ECM/TCM tune review

    Grade- A+ What an improvement! The entire process was as easy as can be. The directions for the process are spot on. Every step is perfectly laid out from start to finish. If there is any confusion about any part of the process, stop and read again...it's all there. I installed a Magnaflow...

    Squeaking suspension.

    The suspension on my Denali has squeaked since day one. I asked them to 'grease' the suspension on the rear of the truck last year and it seemed to work short term. Then I asked a different dealership to do the front with no results. Is there any way to fix this?

    Sold....... Range AFM Disabler

    Latest version- V8.4R1 Model- RA003 Less than a month old. I'm selling due to purchase of a Black Bear tune. This will get rid of the dreaded AFM mode which causes the engine to go into 4 cylinder mode causing the horrible vibration and annoying sound while in such. Here is a breakdown of what...

    Volant 155546 intake installed

    First off, it is not a perfect fit. I checked my phone 3 times with some expressive language about this. But it is in fact the intake recommended for my truck. You will need to remove an additional fender brace to make the air cleaner box fit. This is no big deal. But the holes do not match...

    aFe 54-74104 intake revisit

    Now that I am finally ready to purchase an intake I am reading mixed signs on this intake. BB got the best results out of this intake. However I am reading about several fitment issues. Some place else, at sometime, I read someone cautioned against using an oiled filter which is the 54 comes...

    Did anyone's Range Technologies AFM Disabler cause an upload error?

    I received my monthly email from GMC about the status of my vehicle earlier this week. However, this time it could not upload the information because there was 'an error more than likely caused by something being plugged into my OBD port'. I never used my AFM disabler long term due to technical...

    Anyone else brave enough to admit to this mistake?

    For more than the first year of ownership of my Denali I had unlocked the door by pressing the small chrome button on the door handle with my thumb and then opening the door. One day a lightbulb went off in which I realized if I merely place my hand on the handle it would in fact likewise cover...

    Has anyone modified their sunroof wind deflector?

    My favorite time to open the sunroof is in the fall and something that bothered me last year, is still present...the whistling from the deflector. I have thought about removing it but know it is there for a reason. It seems to allow the infamous booming if held down. I have wondered about...

    Are the resonator and butterfly valve the same thing?

    I've read people saying do not remove the resonator if you wish to go drone free when adding a muffler. However I have also read to get rid of the butterfly valve. Are they one in the same?

    Magnaflow 12909 vs OE

    I still have the OE muffler on my Denali with the butterfly valve open. Opening the valve helped add more sound but does require me to drive in M7 since the AFM is now more audible. This will be no big deal after my BB tune. Question- from watching videos is doesn't appear the Magnaflow really...

    Maybe I will keep my Denali, if perhaps...

    Is there a good TCM tune for the Denali's? I know an ECM tune will remove the dreaded AFM and it's mind-numbing vibration. I can live with the small electronic glitches. It's the wandering transmission and pause to shift from reverse to forward when cold. Has anyone found a TCM tune to take...

    Anyone own a Yukon and Durango?

    If so, please let me know some comparisons. I am really liking the new Durango SRT8. It seems like it should be a nice combination of SUV meets muscle car and tows 8600#. This is important to me towing a 7000# boat/trailer. I have always towed with full sized trucks- F150, Avalanche, Expedition...

    Clunk in transmission from 1-2 shift.

    When starting from cold and traveling down my driveway, there is a slight hesitation in shifting which then causes a loud clunk as it shifts into gear. It occurred very loudly, people turned their heads to look, when traveling down a steep grade a couple days ago. I'm sure it is the 1-2 shift...
