To say he 100% tunes it, I believe he makes changes and you are happy but without a log of you truck how does he do that or how can he maximize a tune. I really don't know and am asking.

BlackBear sends you an autocal handheld. He then asks for the customer to send a read of the ECU and/or TCM of the stock truck using the autocal. He then emails you a tune to install and then you take a log of the truck using the autocal after you install his tune. He then fine tunes the tune using data logs. The logging process is just like with the HPT handheld and computer, however the autocal does not ever require you to have a laptop hooked up while in the truck. The laptop is only used to transfer log files from your autocal to you computer, and transfer tunes from your email to your autocal.

 

I use both the autocal and the HPT handheld on my truck.

Yeah that is what I thought. Also for the people reading these post I will say yet again HPT can do that also. The pro I have has a button on it to record. So plug in drive and push button  get home press stop and walk it inside to a computer email log of and wait for tune to come back. 

 

And again he CAN'T tune the 8 speed trans! At least that is my understanding of it. Correct?

I didn't know the pro version could log without a computer. Good to know. You have the older mpvi1, correct? I didn't need the pro version when I bought mine, and I was able to get a brand new standard mpvi with 8 credits for $350, so I jumped on it.

 

BlackBear can only tune the 8-speed once it's unlocked by HPT, no different than any other tuner out there. Yes, I know Vector and Trifecta (although Trifecta is iffy according to some) say they can tune the TCM without using HPT's unlock service (probably because they know how to unlock somehow as well). Just so people out there understand, just because you buy an HP Tuners handheld does not mean you can tune your 2017+ 8-speed trans. You still have to have HPTuners unlock the TCM for $200 (the "send in your TCM" method) or you have to buy a new unlocked TCM from them for $400.

 

Question for you. If I get my T87A unlocked, would it be easy to get a trans tune that is already written by someone and install it using my HPT? I have a Maggie TVS1900 on my 2017 6.2L.

Which tuner should I use without voiding my warranty??

I think the question should be has any gas vehicle had a warranty problem using a tune or tuner? Otherwise you’ll get a bunch of useless opinions.

Yeah, That sounds better.
Anyone?

Mileguru. That is a smoking good deal on a HPT even if it isn't a pro. I only have pro because I use the O2 analog input. But I can also have used the USB.
Every credit is $50 so that is a steel. There are already many 8speed tunes out there and you can just download them open your tune and compare or straight copy it then drive and see how you like it.

I have the older version yes.

I have never seen or heard of tune voiding warranty. I'm sure it has happened. But in the extreme cases where say the motor goes the deal my point to a turbo, supercharger, nitrous or parts before going threw the software. Again win for any tune that allows you to swap back. Yes dealer can see software was changed but not the parameters of the change. So I have my "soft tune " for dealer visits and I just turn off my boost controller. No codes and low boost. 3be54a11fa65d323dffa73e46b4fa721.jpg

Oh in the picture the square button is a record and stop button the light goes on to tell you it is recording.

Thanks. I bought it when people were dumping them for around $400 - $500 because the MPI2 was coming out, and I had a 20% eBay coupon. I got it from Speedway Motors, so it was a reputable seller. I used 4 of the credits for the supercharger tune and am still thinking of paying for the TCM unlock since I have 4 more credits just sitting on it. I haven't looked on the HPT forum for transmission tunes, but maybe I'll get around to it someday soon.

Earlier this year we got my wife a used 2015 Yukon XL Denali with the 6.2 and 8-spd trans.  I did quite a bit of home work on which tuner I wanted to go with and I landed on Livernois.  I did the Stage 1 that includes a 160 thermostat, cold air intake, and handheld tuner.  The truck is very strong with the 91 tune, and the 93 tune will get it to 460hp and 550 torque.  I'll race anyone who wants to and I like to drive it like I stole it, using maual mode as needed.  With all the hard driving included, gas mileage went from an average of 16mpg before tune to 15.6 mpg.  I do run Royal Purple and AmOil fluids throughout the entire vehicle, which helps with the gas mileage, freeing up a few horse, and protecting it while I beat the tar out of it.

The 160 thermostat is going kinda suck in the dead of winter if it gets really cold where you live.

 

No doubt the tune and such makes these trucks run/drive better but those hp/tq numbers are kinda skeptical without a dyno graph. Those are going to be crank horsepower "estimates" because it's 420hp stock minus drivetrain loss. So maybe 360-380 at the tire. I just don't want future readers to start drooling at the mouth when they read 460hp and over 500 ft/lbs of torque.

Bullshit on those numbers

I live in canada, I have a 2018 sierra Denali with a 6.2.
After reading this thread I'm now not sure what tuner to buy.
I was going to pickup the Trinity t2.
But now, well I don't know.

Ok I'm now leaning to the hptune,

i'm seeing posts on the hptune forum about downloading tunes, is that something for paid customers only?

also where is the best place to learn how to tune and understand what each setting does?

looks like if i go this route i'll have a new hobby.

The down loads are the repository are.mostly stock tune and some customs. Best to learn and do yourself.
Greg Banish is the best he sell DVDs and book on Amazon. But now he has a pay per view also.
Also youtube a had two good guys ceasar something and a guy with a truck like ours with a supercharger. Also the forum is free so start reading. There is a learning curve but once toy get it the feeling is great. You can mod your own. Or with device still have it tuned and use device for data and trouble codes.

    • I just can't think of the exact term GM uses for that higher gvw package without looking at the website but basically sort of a trailering package and I imagine it may also have been created to skirt around the licensing fee differences between a3/4 and 1 ton that apply in some states although ironically I believe in some states its the reverse that a 1 ton is the cheaper truck to license over a 3/4 ton. It makes no difference here in Alberta but oddly enough a 1 ton through my insurance company is a bit cheaper to insure over a 3/4 ton as its based on the insurance statistics they generate.    For sure when ever you do have the chance to weigh your truck and to be fair, try to have the fuel tank full or nearly so rather than give yourself a false sense of the truck being lighter by having an almost empty tank.    In my other comment I was mentioning stock sized tires and partly in case someone was reading this and thinking they could lower their pressure down to what your aftermarket tires are able to do with your empty truck as that is a vastly different picture in the leeway you have to play with for running minimum pressures while remaining safe. I will say also that its easy to see from reactions of truck owners that may have been more used to owning a half ton in the past or a car and be it on a forum like this or in person etc that they get so wrapped up in that placard pressure sticker that they can't get their head wrapped around the fact that an HD truck due to how much it can carry can also vary the tire pressures drastically lower than those pressures ( typically more so for the rear axle on stock sized tires ) when empty vs some car that isn't made to carry much so the tire pressures can't be lowered since it needs almost that much pressure just to carry the empty car.    If I ever do find myself in the states with this truck, I will only be too happy to switch it over to the US measuring system as then I will understand all the dash readings. The only thing that is off for me slightly with US measurements is US miles per gallon as I grew up with the Imperial gallon and to this day up here anyway speak in Imperial miles per gallon ( I don't do that on this forum though as that would confuse everyone for no good reason ). 
    • Yes that's right, it's the upgrade that includes the overload spring and all that stuff.   Someday when I'm empty and going by a scale I'm going to stop in and get some weight readings.   Exactly  you should have the ability to change individual settings, in in Canada so I'm driving with kph but then I'm stuck with kpa when I want psi lol    
    • You must have that upgraded gvw package which is only available or at least was in 2025 with the diesel engine for the 3/4 ton and that gave the truck physically the larger 12.0 ring gear rear diff and the 3500 rear spring pack. There is a difference in what the diff housing looks like externally as one tell tale and also your truck should have the upper overload spring pack and the frame pads that the pack goes up against.    The pressure the tpms system kicks the alarm in on a stock setting truck, that is a good question and was just from what I recall but I doubt I made any notes on it as I knew for the rear that it was not at all what I was after regardless either. Being that you have a diesel and if running on stock tires the minimum pressure on an empty truck seems to be around 50 psi from hearing of those that have weighted the front axle but the rear axle is very similar in weight to a gas truck and again a near empty truck on the rear could go down to 35 pounds at minimum. However the weigh scale is the proper way to know for sure as a guide.    As to changing the readings on the dash from metric to the US measuring system, oh yes that is done easily but what I was attempting to explain was that I can't pick and choose items I want to have in US and those I still want in the metric system at the same time as its either all or none. For example lets say you drove into Canada and switched your dash over to metric so your speedometer read in km an hour, well then your reading kilopascals on your tpms readout and your wife looks over and says what the hell is that saying in the tpms screen and you say "darned if I know, I think its Chinese" !
    • This is partly why I decided to have switched over to Amsoil SS as a way of hopefully preventing the buildup of the sludge/carbon on the pistons and clogging of the oil control rings and the carbon that would cause the compression rings to stick in their grooves as well as stay cleaner up top of the heads in the valve train in the first place, an oil that has tested better by third party testing over typical shelf oil and also doing my best to run relatively short OCI. However in saying that I don't think there is any way to easily prove the oil I was using prior allowed for a buildup at the OCI I was doing, nor in the other direction to make claims the Amsoil is keeping everything clean either. There really isn't a window into the engine is there to know anything for certain even if oil samples were taken for example that showed still healthy oil being dropped out of the oil pan other than engine tear downs that extensive and expensive testing of oils does to actually visually see what is really going on inside the engine. I wish there was some easy method of seeing what is going on but I don't happen to be aware of that if there is.  
    • My truck is a ¾ ton but my placard also says 80 for the rear tires, I think I might have the upgraded suspension to the 3500 series maybe.   I put my air down to 60 and the light was still on, and there was no way I was putting over 60 psi in the rear empty and not towing because I knew the actual number Toyo gave me and I didn't wanna ruin the center of my tires!   And you actually can change it in the settings from metric or is and it will show kph or mph then when you go into your tire settings it will be either psi or kpa, but it would be nice to just change it directly on the tire psi page
