I did black bear on mine and the shifting is awsome. They calibrated the spedo for my 35s, disabled the 4cil mode, everything calibrated for my intake and exhaust for optimum fuel air ratio using 91 octane. Well worth the money.

+1 Following to see where this goes. I've got a '18 6.2 8 speed Denali w/ Volant CAI + Borla GMPP specific Touring Exhaust on mine right now leveled w/ 33's. Will be looking to add in a Black Bear tune and maybe headers within the next year or so but eager to see what the results look like.

Just got mine. first thing you need is the unlock code which i sent in last night.  Then I will be able to read the file to send it in for tune.  I am in Disgust with GM over this.    I have fought for 8 months for them to resolve my Fish Bite/Chuggle.  the local dealer has been very helpful but their hands are tied because GM will not address the issue. So i am leaving it in the hands of Professionals who care about their customer.  I just want the truck to drive properly, and shouldn't have to buy a tuner to do that, but i have heard nothing but great things with Black Bear so I cant wait to see the results.

Quick update, 2017 has an added security code. Needs to scan and link first, then load the code to the laptop to send in and get an unlock key code before you can read your files.  Just sent the files in now and i will see how long the turn around is, trying to be patient...

Subscribed as well.  I want to tune my 17' 6.2/8 speed Sierra, but it's my understanding that they can not tune the 8 speed and engine in the same tune.  Something about having to pay for double credits. IDK, let us know.

Tune is in! initial verdict is that it doesn't do the fish bite anymore!  may be early to tell, but just on my drive to work it felt 100% better!   Shifting is better as well. Doesn't shift 3 times before 30 mph and bog out.  holds the gear better and doesn't bang on deceleration.  Didn't notice much for power gain, but truck is stock and haven't played with it much yet. i would like to see it fry the tires off if i want, but that is expensive, lol!

glad your truck driveability has improved. Post a update after you put some miles on it.

      Trim level custom/pro

      By Another JR · Posted

      Are you going to take long trips in it?  If so, try out the seats in the various trims. For me the lower trim level seats were not comfortable.

      I have a 2016 that I bought new and still own. I'm around 129,000 miles now. The biggest problem was a transmission failure about 2 years ago around 95000 miles. No warning, just failed while driving down a back road. A reman GM transmission installed and it's been fine ever since. A few other minor problems along the way. I am in no hurry to replace it. It's been paid off long ago and do plan on driving this as long as I can.   I will admit I am leery about all the additional electronics in the newer models and feel that it is just more potential problems. I think there's actually more than I would have wanted in this 2016 but so far so good. I think even if something major like lifter failure happened, it would still be cheaper to at worst, drop a new engine in than buy a new vehicle.

      OCI, not when but why?

      I’ve own several successful businesses. I’ve bought homes and lived in different states. I’d witness several generations buy homes and survive in different economic circumstances. You get awful sippy when people have different experiences than you do. You live a life. I’ve lived a life. It seems our experience has been different. You can point out generalized statistics. Some people learn how to thrive when the odds are against them. Living in different states does make a difference in a persons quality of life and economic outcomes and opportunities. That’s a fact Jack. It’s my truth, my life. Hard work and long hours the right environment made my families life easier. And yes moving to a different state increased the odds of that happening. Stats are generalized. People who thrive don’t make excuses. They beat the odds. Others get mad and point to those statistics. I guess that’s you. My post pointed out how you helped people beat the odds. Somehow your panties got in a wad. Go figure.

      Good question, I don't remember for sure but I believe it was the HD. I will check and get back to you.

      Point of the post sir was that while both wages and cost are rising EVERYWHERE; the cost is rising faster EVERYWHERE than the ability to buy EVERYWHERE. We're not going down the location rabbit hole. I'm aware of what economic migration is. I've lived in four states including Texas.   It's what "Purchasing Power" means.   I'm not telling you what I think. I'm telling what the government, your government, data shows.   It wasn't an argument. It wasn't a suggestion. It was a statement of FACT. You are absolutely entitled to your own opinion. Your not entitled to your own facts. If you and I were, they wouldn't be facts.    fact /făkt/   noun Knowledge or information based on real occurrences. "an account based on fact; a blur of fact and fancy." Something demonstrated to exist or known to have existed. "Genetic engineering is now a fact. That Chaucer was a real person is an undisputed fact." A real occurrence; an event. "had to prove the facts of the case." The American Heritage® Dictionary of the English Language, 5th Edition • More at Wordnik   If you'd like to disagree call your Senator or Representative and let him know his departments are in error. But you and I? We are not doing this.
