I have had my truck back and forth to the dealer for its crappy throttle response poor shifting, engine lugging along at low speed several times already....the last time they drove it for days and said "its the same is all the other ones" there is nothing we can do to change it or make it any better....I discussed a tune with service writer who understands the way i feel and said he would not hold it against me if i had a warranty issue if I was to tune it to make it run better, which makes feel a little better about going the tuning route. (hopefully he keeps working there a long time)

 

So after all I've read here about tuning etc, whats the opinion of the masses

Diablo or Blackbear?

 

I will most likely do a custom tune thru Black Bear or Diablew...just need to know which device is easier to use, which is easier to set back to stock...I don't want to have to get to technical with changing little settings. I just want to download and go without having to worry if my truck is going to start and run after i go thru the process...

I have either, Bully Dog GT, not that great. Not much options other than removing Brake Torque Management, change tire size to correct speedo. There IS a difference when you tune it with this low end canned tuner, but does not improve 0-100km/h that much.

 

It does make it more torquey feel, my 0-100km/h is still only 9.4s at 750m above sea level for a 5.3L 3.42 with crew cab

 

My buddy is getting a tune for his same configuration in a shop today, I am hoping to see some dyno chart results. of before and after.

I used hypertech, I was happy with how my truck ran on E85 shifting was my main complaint. I reduced the TM raised the shift points and top end a bit. The results was a different truck performance wise and still had the ability to use different grades of gas when traveling. I did remove the V4 too, a must with tuned exhaust, lost one mile per gallon on trips.

I've had HP3, Diablo, and Blackbear tuning. Hands down, Blackbear is the best. Now you can use their hand held tuner to load and unload tunes. You could have a mileage tune, a performance tune, a towing tune all at your finger tips if you desire. If your lucky enough to go to one if his meets, you can have your truck tuned in person with him making minor adjustments to suite your truck specifically. You can also do some data logging and get the same result as an in person tune if you want the best possible tune for your truck. It data logs parameters that blackbear can use to adjust the tune specifically for your truck.

 

Hands down, Black bear tuning for GM trucks.

I just got my 15' tuned by BlackBear and it feels alot better! The custom map is hidden within the computer so if i take it to a dealer it would be hard for them to tell if i have a custom tune. He adjusted my speedo for 35s, throttle response is awsome, shifting points were moved, limiter is now set at 130mph, V4 is gone and works with 89 or 91 since my truck is not flexfuel i cant run E85. Plus if youre LE or Military you get discount!!

Hmm I'm consistently between 7.2-7.5 seconds 0-100 with same truck and diablosport.

 

Also have slightly better city and highway mileage.

 

Blackbear would be the way to go for performance for sure, if you can afford it and find somewhere to meet up with them.

Can I do a custom tune that gains some performance but still uses 87? I really just want to get rid of the crappy stock tune that GM puts in there and make it drive like it's supposed to.

Or are all the custom tunes going to require 91?

Yes, you can have a performance tune on 87.. it's just not as strong as the 91 tune would be, but still better than stock! Personally my 2015 truck seems to run pretty good so I've not felt the need for a tune. This would be the first truck I've not tuned. (yet)

Alright guys...I know there is a lot of tuned trucks out there. Any more pros and cons to the Diablo vs. Black Bear?

You can squeeze just so much performance out of these motors. So for the basically stock motor, there probably isn't a major difference between the two. I've installed the Diablo tune and find it very easy to use. I have a custom tune from Lew and my truck performance has improved 100% I would probably feel the same way about a Black Bear tune. Reinstalling the original tune is a 10 minute process and my processer has always worked flawlessly. No doubt Black Bear users will tell you the same thing.

The real issue is, are you ready to pony up if your engine experiences a major failure? Regardless of your dealer's good intentions, GM requires the dealer to submit all of the recorded data of any vehicle that has a major breakdown. They (GM) makes the decision as to whether or not to honor the warranty, not the dealer. If you tune and drive in a normal manner you'll probably never need to use the warranty. And if you do experience a major issue and the record shows that you didn't exceed GM's performance specifications when the failure occurred, they won't have any basis to void your warranty. If you drive like an 18 year old street racer, well, be prepared to pay out of pocket.

Well I'm to the point that this truck is so crappy to drive that I've already considered trading it in..but i just cant bring myself to take an $8-10k loss on a $52k truck with 7,000 miles on it...so i figure if I'm stuck with it, I might as well get it to drive like it probably should have from the factory or even better...

I'm way past the 18 yr old street racer point of my life, so hopefully i don't have to worry about a catastrophic failure. But if i do gamble, it still works out to be about as much as taking the loss now on trading it in....

I just HATE getting in this truck every day...from what I hear tuning it makes a world of difference, and that's what I'm hoping for...

I just want to get the all the input on which way to go with a tuner that works for me before making another bad decision, like the one i made buying this truck in the first place...

I've never had to use a warranty yet. All of my major failures have come after the warranty expired so I didn't consider it as big a risk as some folks do. I agree with you, these trucks aren't tuned for performance, they are tuned to appease the EPA gods. And of course, the consumer suffers. When all of this warranty stuff hit the fan, I reinstalled my stock tune. That lasted for about 10 miles. I made a rolling left turn and the truck went back and forth between gears trying to make up it's mind as to were it wanted to be for about 30 feet. I went directly home and reinstalled my tune and never looked back. Screw the warranty, I want performance. Get the tune. It doesn't matter which one you get. They all have been on the market for some time now and are proven performance enhancers. Then you'll have a truck that performs as well as it looks.

You can get a Blackbear tune without meeting up in-person. The Autocal can log the data and Justin tunes the truck based on the data logs. It works pretty well.

If you tune it to wake it up for daily driving performance, what happens if tow a boat and don't change the tune....does putting the truck into tow mode create any issues?

Guess I will try Blackbeard this time because I can't get the Diablo to work on the 2015 and you can't get any support from them lately!!Tried of calling and getting hung up on by recording or sit on hold for a hour

      Pulsating Noise 4Cyl Mode

      By zibzer2 · Posted

      2017 Silverado L83 5.3l 6speed transmission Hello, not a new member but havent posted in a while and my old signup info isnt working so had to create a new account. anyways, I have an issue with my truck and hope someone can spread some light on whats happening: -when it goes to 4cyl mode it makes a clunk sound (but not when coasting or going downhill) -when in 4 cyl mode and under load it makes a load pulsating sound (not a tick). -goes away completely when in M5 gear or when plugging in an AFM delete. Im guessing it is one of 2 things but im not convinced of either to be honest. 1. lifter stuck in v8 mode 2. torque converter shudder realistically it doesn't seem like the TC as there is no physical vibration , and it never happens in v8 mode. but maybe? and wouldnt a lifter make a sound whether with load or not? any ideas let me know please. thank you!

      Some Assembly is Required

      By Chuck FB · Posted

      Which has made me wonder with the various engine failures of a few brands in the last few years, is it sub par materials such as lifters etc causing failures, or bearing clearances on the crank etc or perhaps bad designing of an engine physically or causing too much load on the components due to the hp/torque they can push out of them. Or is the oil viscosity and additive package of current oils or a lack of oil flow by an oil pump not able to supply sufficient oil at idle or under high load at low rpm. Or is it every item I listed that combined together has pushed the limits so far to the left that there is hardly a margin of safety left and add in some fuel dilution and too long of an OCI and premature engine failure is the result ?.

      He is not saying that an SAE *W20 will have more viscosity than a *W40 due to MORE VII polymers. He is saying that although multiple *W40 may post in the PDS the same or similar 100 C and 150 C viscosities that the blenders choice of modifier TYPE and AMOUNT to get his chosen base to grade will not give identical real world viscosities in shear and at temperature. All will pass the SII test but not all will pass the 100 C HTHS (unpublished value) testing the blender does and relies on to get the required by law "percentage improvement' referenced to his last great work.    Tis the problem with the lie. Once told others are required to support it.

      Parking Brake - Automatic Engagement Questions

      By PunchT37 · Posted

      I have a `25, 1500 that auto sets on incline. Never knew that at first. I have the electronic shifter. Just think if it didn`t do that? Unlike a mechanical shift that you can muscle out of park, how would you get this thing out? That would be a problem.   What I found out later is, I don`t have to push the button to release. Just put it in gear.   Setting parameters? Don`t know if it`s possible.

      Parking Brake - Automatic Engagement Questions

      2023 GMC 3500 HD, SLE, 6.6L Gas, 4x4, 6 Spd Options:  SLE Convenience Package; Driver Alert Package 1; Spray on Bedliner; X31 Off Road Package; TRAILERING MIRRORS, HEATED POWER -ADJUSTABLE, AUTO DIMMING, WITH TURN INDICATORS WHEELHOUSE LINERS, REAR INC. REAR AXLE - 3.73 RATIO INC. GVWR, 11,350 LBS. (5148 KG) INC. FRONT AND REAR PARK ASSIST, INC. ULTRASONIC     I have been launching my new boat and noticed some things related to the parking brake.. I usually set the parking brake (habit) when on flat ground for typical driving.    When backed down on the launch ramp to launch the boat and I place gear selector into Park, the parking brake activates automatically. My second nature is to set parking brake manually and noticed I was turing the parking brake off.  The parking brake appears to be setting itself automatically.   I looked all over my owner's manual and only found references to being on an incline and manually setting parking brake, or at times parking brake will be auto engaged, but nothing specific to my situation.    When is the parking brake automatically engaged?  Under what specific circumstances?  Can the auto set parameters be changed?     I like the auto set feature.  It would be nice if always engaged when shifted into Park and released when shifted out of Park (like my wifes 2025 RAV4).   Thanks!
