Black Bear tune vs. Hypertech

[Justinlw]

If you mean a code reader they do and you can check it yourself.

What he's saying is that Justin will analyze your engines running condition (log file), and let you know if you have any sensors out of normal range causing performance loss. A code reader won't do that.

 

A shelf tuner will dump the same parameters on a stock truck, as it will on a truck with a cam, higher compression, and head work.

 

Justin will tune to match what your engine needs specifically. He'll also retune when you make changes, so you get the most out of your upgrade purchases.

 

There's really no comparison. You're not going to find anyone that says there's anything as good as a custom tune.....except maybe a hypertech salesman.

I would never say can is better, just pretty good. Much better than stock.

I did a lot of diesel racing in the past, and watched a few guys learn the hard way about edge and diablo programmers. Too much fuel with aftermarket injectors = high egts = melted aluminum pistons. Saw a few others lift heads from overboosting. I know turbo diesels are a galaxy away from a NA gasser, but it still left a bad taste in my mouth. Tune FOR your parts, don't throw one on top of them.

What is the difference between the Autocal and EFI Live?

[RyanbabZ71]

Efi live is the software. The autocal is the handheld that transmits the program to your vehicle. Otherwise a laptop with efi live software can transfer the tune

Just get BB autocal. Justin is the best gm tuner.

Just curious, what do you gain from doing this? What does it do to your vehicle that makes it better exactly?

A tune will adjust several parameters on the truck such as, shift points, timing, toque management, fuel tables, afm (v4 mode) and such. These can be fine tuned to give the truck more performance and better drivability. The factory tune on these trucks is pretty conservative and really favors fuel economy, sacrificing overall performance.

 

The handheld tuners as they are referred to on here, Diablo, Hypertech, Superchips, Bully Dog, all adjust several of these parameters in your truck. The problem most find with these is that its a general tune designed to work for several vehicles so performance gains can be hit or miss.. Some like Diablo and Hypertech are pretty popular on here and seem to have favorable results.

 

However, there are tuners like Blackbear performance that use a software called EFI Live. This is one of the best tuning softwares out there and is also used to tune practically any kind of vehicle that uses obd 2. Blackbear will specifically make a tune for your vehicle either by dyno testing or using a log created by your own vehicles sensors. They will then read this log and see where things can be changed or added, and using your input will create a personal tune for your vehicle. So if you have a headers, a full 3" exhaust, intake and maybe a cam, they can tune your truck to make the post power on these modifications.

 

Now there are many other people or companies that do this. For example if you go with any of the Diablo tuners a guy called Lew will also do a similar service as Blackbear.

Hypertech work good for what I wanted, firm shifts, no V4, and raising the max speed. It helped with the sometimes lazy throttle response. I agree with the last post as far as custom tune. I'm debating a S/C, then I would do custom

I'm going to add a CAI and exhaust system on my truck. I really want a BB tune bad. Just nervous about playing that warranty game.

Get a 2nd pcm and swap it out when going in for service

[5RWill]

Where would you find a second PCM?

[02suburbanZ71]

I think BB sells them

For your year vehicle, the AutoCal would be needed.

 

So long as you returned the tune to stock for dealer visits, you are good to go.

Old thread but wasn’t impressed with blackbear at all for the money. Things in the junk pile now
