Cant wait to get my tune as well!! I'm going with a local performance shop that has tuned all of my trucks...the beauty of living in south Texas is the plethora of performance shops that specialize in GM trucks!! Love to be from where the truck is king on the drag strip!! haha

 

I got a reasonable quote as well for jumping to 4.10s from my 3.08s for both axels installed as well as a true trac for $1800....plus my 1 7/8" headers are on the way from ARH.....I need to get home soon!! workin these oilfeilds is nice but all my goodies are down in Texas!!!

 

 

 

anything else that I would be missing?? truck is leveled on 33s right now and will go 35s later.....plan on procharger for summer 2016 if all goes well.....and i dont dump this one for a 2016 with a 6.2L since it's almost paid off!!!

I'm fairly new to what's involved in custom tuning a truck.

I have put down a deposit for a "in person" tune by Black Bear this January in Sacramento.

What is the difference between a "in person" tune and purchasing their AutoCal and tuning a truck yourself as you guys have been explaining?

Is there a benefit with a "in person" tune besides meeting both Justin and Jerrod?

Thanks in advance, Rich

Puttnutt,

Justin tuned my truck on the fly with his computer hooked up. He had my AutoCal preloaded and fine tuned a few settings once it was installed. I didn't have it before so I can't comment on how it would be sending the recorded info back to them and installing their tune yourself. Great people to deal with.

I am still evaluating my tune that Justin reconfigured for me and all I can say is he is doing a great job and has my transmission shifting very snappy. I had him do some readjusting after my transfer case update and I wanted my transmission to shift according to the rpm's of the engine; softer pedal lower rpm's, full pedal high rpm's...

I have only driven maybe 50 miles but so far I am liking that adjustment...

One thing I am going to write to him about is a very small moment of "non responsiveness" as she shifts. I do NOT have the V4 mode turned off and I notice it at each shift. After I plug in my range, it seems non existent.

He has reprogrammed my speedometer for the taller tires but I do regret not buying the correct tuner... I cannot make any smaller adjustments so for every small change I have to write Justin... My bad!

I'm really looking forward to meeting these guys in Sacramento next month and even more so, tuning this truck so that it drive as it should....

You will love your truck post tune. Justin really took his time and dialed my TCM tune in the way I like it. Yeah you will pick up a little HP but the drivability and no more bang and clang is worth every penny.

Is it strange my truck had 500 miles on it and i contacted BB? LOL. The 08 sierra i had shifted real nice after the BB tune. It ran 170,000 miles with the same tune it.

Now, BB is waiting on the ECM tuneability (TCM is available)for the 2016 but, living in Canada, perhaps the flash counter may be an issue as i don't know if they have to prove anything to void the warranty and with 99,000 miles of warranty left i am not sure i want to screw that up.

Looks like a few others on here were nervous too when they still had lots of warranty left.

Let me know what you find with the V4 mode, Mine is enabled also with the performance tune - sometimes when it switches in and out of V4 mode it does something strange with the torque converter lockup.

I haven't wrote to Justin yes, as the Holidays have brought a ton of stuff to do... like having to reschedule my dental appointment because they were running late.

I sure got a dirty look when I brought the wife home a custard doughnut today and she found no custard inside...

I do run the Range mostly within city like driving, but have notice that the small or short hesitation is more noticeable when the engine is colder over being in running temp.

Not relevant to this post but I am getting a negative view to my Cooper Discovers tires... With just a little rain the spin at start... I want my Dueler Revo's...

Do you have your new tune up and running now? I just ordered mine. Sounds like quite a process from start to finish?

I have not contacted Justin about my 1st to 2nd shift issue. It seems the cold might be part of the issue so I am still evaluating... As for the rework that I had Justin due to allow trans shift to correspond to throttle pressure, I really like it. When I take off at a slow pace my trans shifts about 2200 and doesn’t make the engine whine out to 4000 or so…

I am getting my desktop ready to go into the shop this week... a few issues need be corrected... The issue with the possible V4 mode is on a back burner right now, but using the “Range” does seem to help.

It looks like most people are running tunes but also have quite a few mods. Has anyone done a Blackbear tune on a stock truck? I'm just making sure my money is well spent. My goal is to clean up the laggy/clunky shifting, disable AFM, and potentially gain a little power. Is anyone extremely happy their Blackbear or other custom tune on a stock vehicle? Eventually I'll do intake, headers, exhaust. But for now just looking to improve the shifting quality.

Many many people have tunes and nothing else. Quite frankly, once you do tune, that's all you really need. There is not problem tuning a stock truck without having additional modification. If you do end up doing other mods in the future such as intake, headers, etc., your tune can be modified to accommodate those modifications and net you the maximum results.

 

Blackbear is top of the line. Many members on here have and are currently using blackbear. Another one is Diablew tune. Takes the Diablo canned tune and does a professional tune upgrade. I went that route and I'm very pleased.

 

Hope that helps.

To Hauz_Z71, I agree with Kerrslight's comments. A tune on an otherwise stock truck will give you a bump in performance, shifting and possibly a slight increase in fuel economy. It is hard to explain, but you will enjoy your truck a lot more. It will act like you just took 1000 lbs out of the bed and then drove it. I personally feel like GM is handcuffed by the EPA and government regulations. A tune will give your truck the ability to perform like the engineers intended. The difference is impressive. BUT, you have to ask yourself if you are prepared to forfeit your factory warranty on the engine and drivetrain for the benefits of a tune?

 

So far, I have been fortunate. Have tuned my last two Corvettes, a 2002 and a 2010 and a 2008 Sierra Denali 6.2L. All had headers installed with the tune. Not one of them had any engine or transmission problems related to the tune. The 2008 Sierra did need to have the transmission partially rebuilt and GM covered it under warranty at 35,000 miles. It had a factory defect in a weld on the 2-3 clutch basket that had nothing to do with the tune. I told the dealer it was tuned and they still covered it because it was clear there was a defect in the weld from day one. All were tuned by Chuck Mosello (Chuck CoW) from Corvettes of Westchester. Nothing against, BlackBear. They have an excellent reputation. If not for previous experience with Chuck, I would go with BlackBear. Both use EFI Live and an AutoCal. The AutoCal allows you to connect to your vehicle and send scans to your tuner via your PC or laptop. Then your tuner reads and analyzes your scans and sends you a tune via email for you to put in your vehicle. It is a custom tune specific to your vehicle, the gas in your region and how your vehicle is used. Good luck with your decision!
