Hey guys just wanted to see if anybody else had this problem i have a 14 sierra 5.3 it's tuned by blackbear I really like the work Justin did so I recommend him. The truck only has 10k and it came up with a couple of codes this morning P2635 and P018B I want to take it into the dealer to see if they can check it out what are the chance they see the tune I flashed it back to stock and the codes went away but I'm sure they will come back up when the truck gets cold again what would y'all recommend?

Return it to stock and see what happens. Sounds like a fuel pump issue or a fuel pressure regulator issue. It couldn't have been caused by the tune so you should be alright. To claim otherwise is complete BS.

I have received numerous PMs asking about my tune, so many in different threads, I don't believe I could find them all, so I thought I would just initiate a seperate thread to address it. This may be

I just had Black Bear tune done and wow my truck at full throttle shifts into 4th at 100 mph. Transmission shifts so much better. Throttle response is fantastic. Best tune I have ever had done.

Ok, there seems to be a little confusion and a lot of misinformation passed around the internet that WILL eventually bite one of us in the butt when they go in for a warranty after they get their truc

I just had my fuel pump go out on my 14. Around 32k miles on it. I use the Diablosport tune. I just returned to stock prior. No issues at dealer, replaced it under warranty.

Shoot a datalog and an email to the guys, they can check into it.

I had the recall done today and I am pretty sure I lost my tune. The throttle feels much less sensitive was the first clue.

 

Can I re-flash using my Autocal, or does that negate the point of having the recall done in the first place? Is there an update tune that incorporates the recall?

Shoot the new tune files to the guys, and they can see if any major changes were made.

Any handheld tuners for the 2017 GMC trucks that remove speed limiter?

Not a handheld, but Black Bear Tuning should be able to help you.

 

I can't give a review just yet, but they will be in Austin come Nov. 12, and I plan of having my truck done...hopefully enough people sign up.

 

IF I get it done, I'll be sure to give a review on my 2016 Z71 RCSB w/5.3.

Well tomorrow is the 12th, and I'm looking forward to the tune massage!

 

Excited to feel how much difference this tune will be in comparison to driving in trailer mode.

 

At minimum I hope the helicopter (AFM) will die in my truck, it is so annoying!

 

Updates to follow.

Well I just got my tune massage done by Justin @ BlackBear, and what a difference it made!

 

First off he took his time to explain everything about the AutoCal, which most I already forgot, but he does give you a link to instructions and in my experience he or Jarrad always responded to my emails in a very reasonable time

 

What is cool about doing it this way is, he will sit in the passenger seat with his laptop as you drive and will make adjustments as needed. If he makes it too aggressive for you he can change it instantly, if not aggressive enough he can change that too.

It was amazing to feel the differences as he made adjustments...first he dumped the AFM, so no more Black Helicopter sounds, then he worked on the transmission upshift/downshifts, and next was the throttle response.

The shifts are now crisp and throttle response is immediate, and if for whatever reason I need to change something I just need to let him know and he'll send a link for me to download on the AutoCal. My 0 - 60 time according to my info on the dash (DIC) I gained 1.5 seconds....BANG for the BUCK!

He also made adjustments for my CAI, and programed my truck for 89/93 OCT.

 

This is well worth the $$$ and if I was going to do it all over again I would do this tune first, and then the true dual exhaust and CAI.

This was much cheaper than the exhaust and CAI, and I got more performance upgrade from the tune.

Considering the bang for the buck on true performance, this should be a must do on anyone's list of Mods...you won't regret it, and at worse you'll look weird driving with a big smile on your face.

 

Caveat: This could cause lower mpg & excessive rear tire wear due to the direct relation of the right foot and sense of feeling and hearing...then again if you can control the right foot and not let your feelings and hearing affect you, you should get a little higher mpg & normal tire wear.

Thank you for the review! Enjoy your new tune!

Just giving credit where credit is due!

 

Oh I'm enjoying it very much...everyday it seems to get better!

The throttle response is much more responsive today then it was on the first day...BlackBear Tuning should move to TX, it would be a good strategic business plan to reach more customers with a shorter travel distance = less cost...hehehe! :thumbs:

We are a small business, so word of mouth is our best marketing!

 

The guys are in Texas quite a bit, but I don't think moving there is in the cards. :ninja:

The guys have been to Denver a few times, but it is not on the current calendar. They can get you taken care of remotely if you were interested in that route.

I would like that. Should I just contact you at black bear performance or is there another number for contact and details.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Sad thing is that this doesn't have to be the case. LSPI can be solved without a reduction in TBN. Swap Ca for Mg.  Cats are not a issue if the OEM can get a ring and valve guide seal even at SN levels of SAPS. Dizzy is purring like a kitten with a bowl of warm milk. 200K of Full SAPS oil and zero detonation issues and nice a clean inside and out. This shouldn't be an issue. It isn't 1920.    Tell ya what AMSOIL SS is excellent at, internal cleanliness. The new formula is even a step up from their already outstanding cleanliness levels. Can't say the OEM offering is quite that clean. There marketing suggest the SS is cleaner.     That is the only defense with at shelf oil. Nothing wrong with them if you ignore the marketing and OEM 'recommended' OCI and use a thimble full of common sense. 😉 You go sir.

      Roll up bed cover experiences

      By StingerZ16 · Posted

      I started with a folding cover by BAK PAC on my 2500. It went bad after close to 5 years. Bent and vinyl coming loose. Contacted BAK and they gave me a very good discount on a Revolver. Had it a number of years. Mostly outdoor storage. Some garage storage. Vinyl started to come loose. Still under warranty so they replaced to cover. Sold the 2500, bought the 1500 and got another revolver for it. Had it a couple years now and no issues. I store it indoors. Got a bit of discount when buying it as well. If you are seeing problems, contact BAK or real truck and let them know. Customer service was pretty good. But I think they changed their warranty.

      Towing In Loose Gravel

      By Chuck FB · Posted

      I agree, there is no one answer fits all as every rig is different, one may be pulling some little aluminum fishing boat while another is towing a monstrosity that weighs a lot and hopefully the owner if the rig has some prior experience to know what drive mode they should choose.    It also struck me and this is from watching a few of those boat ramp escapades videos in the past, Ford being one of the vehicles that has the auto front axle hubs and sure enough its found out that one hub has crapped out and won't engage and may not have manual hubs to even select on both sides so they are on the boat ramp stuck with no four wheel drive and spinning .... they flat out need a tow to get up the ramp and deal with the vehicles new found issues. That can happen to all brands of pickup, finding out either four wheel drive or 4 low isn't working right at the time its needed it to work as some electronic crap has failed.

      Towing In Loose Gravel

      By Chuck FB · Posted

      Its possible you never had the joy of the crappy boat launches we tend to have around here or really some of them are just grades down to the river if its a river scenario and the conditions change all the time with the river levels and silt deposits. Some of the lakes we went to years ago, there was no such thing as a cement pad that went down into the water that the trailer stayed on, it was gravel maybe up to the water line and then duck crap much beyond that so sinking the boat tires into mud. Of course some of the more established lakes had a cement bar type boat ramp but sometimes it was covered in green slime closer and certainly within the water and a two wheel drive had all sorts of fun if one had to touch that slime with the rear tires.    A neighbor of mine had made a comment years back with his chev truck that was probably about the same year as yours but a half ton extended cab 4x4 and he a a fiberglass boat with an inboard so it wasn't a feather weight and he had gone out to one of the large popular lakes in the area and don't ask me how this happened but he was in two wheel drive as he figured he didn't require four wheel drive for that boat ramp and somehow upon pulling the boat out he twisted one of his drive axles. I suspect it must have spun and then grabbed on the cement ramp and shocked it to the degree of twisting it. He would have had the standard 8.5 or whatever it was axle housing as the 9.5 ring gear like my truck has also has larger drive axles as far as I know. Anyway he was feeling a vibration driving home and had it checked out and a shop found that the tire/hub was wobbling because of the axle had twisted so in went a new drive axle. After that bad experience he said he made sure to put it into four wheel drive to lower the stress on the rear axle. Of course that is where an HD truck can handle a lot more stress and no doubt these newer half tons with their larger ring gears probably have larger drive axles as well to match vs back in the day.

      2027 GMC Sierra: Official Discussion

      By asilverblazer · Posted

      Desirable - as in does someone WANT one, aspire to have one. Could reasonably buy any car they want and CHOOSE these instead.    I didn't watch the video, why did they win?
