BB tune?

[grilled2003]

I have seen a lot of you talk about BB Tune and I
wanted to ask what does the BB Tune do and how
does it work?
How much is the cost for 07 Tahoe?

Check out www.blackbearperformance.com, lots of info especially in the FAQs.

grilled....dont ask questions, just do it and you will have no regrets

It was the best mod I have done. Justin is a Pro and will make you wonder how you enjoyed your truck without it!!!

If you have a 6spd transmission, wait until there is TCM support. Still waiting....

 

[InTruckDesign]

There is 6spd support, but since the tcm is part of the trans. only an in person tune can access it.

 

[JennaBear]

Some of our customers have purchased the V2 (which supports the 6spd) and allows for email tunes from Justin.

 

[mtbennett24]

Indeed. I should have specified. No TCM support for remote tunes unless you buy the FlashScanV2. Other option is live tune until the AutoCal comes out.

Their website linked above is the best way to get an idea of what you want. After looking at the website, I emailed Justin, and was able to ask him some questions that I still had. He answered quickly and throughly, even though he was busy. I was lucky to figure out what U wanted, then get it tuned two weeks later. LOL.

I love the tune, and I really dont think there is a better one out there. I believe this because of one reason; JUSTIN. He knows how to make the vehicle come alive, and drive the way you want. I did an in person tune, and it cost me $250.

The ease of acceleration makes the Yukon driving extremely easy to drive in town. Then when I put it in sport tune, she comes uncunted and flat out runs.... and runs FAST!!!

You should see what it does for a 6.2 6-speed truck.

do it...do it. all jokes aside, have you read ONE post anywhere on here from someone who did it and regrets it or has something negative to say? best mod ive done so far. i love it and so does everyone else who has one. do yourself a favor and schedule one ASAP.

 

[07-fivethree]

Yea, seriously. Its the ONE mod, that you will honestly be mad at yourself for not doing sooner, because it is that badass.

I bought the V2 to be able to reflash my truck in case the dealer blew up my tuning. It's a pain in the ass learning how to work it, getting logs for Justin to look at, and then flashing your own truck. I still need to get him another post tune log to maybe do another tweak on the transmission. BUT, today I got the first opportunity to test the tuning against what should be a perfect measuring stick. I lined up with a NBS Escalade that would be the same 6.2 6-speed drivetrain as me. From zero to 85-90 mph I put AT LEAST 5-6 lengths on him and it was getting worse the faster we went. He was sure I had a blown 5.3 until I showed him it was a stock 6.2 with nothing but a BB tune. To top it off, his truck was 2WD and mine is a 4X4 with lots of junk in the back including the rear seats and every possible option. Everything else is a waste of money.

PS: Try that with a Superchips or Diablo tuner. Good luck.

 

[JennaBear]

The transmission a bit more like you had hoped it would be?

 

[Fast55]

Yes, but still not what I'd like. I posted the problems in the Diablo tuner thread and it's a factory problem. the TSB fix made things worse if nothing else. Justin's tune has helped, but not solved everything. The upshift is harsh if you roll up in speed and have to get out of the throttle just before, or as it shifts on the 1-2 or 2-3 shift. It happens a lot in traffic. I still have the flair when it's not all the way warmed up, or even if it's warm but has been re-started after parking it and hasn't been through a couple of up/down shift cycles. It's weird. I wish I had never had them do the damned TSB "fix". It's also a little harsh on up and down shifts while in tow/haul mode. They know there's an issue with the 6-speed trans since they issued the TSB, I just don't think they know what exactly is the problem, and they sure as hell don't know how to fix it.

Gotcha, yeah the dealers sometimes will just use a band-aid.
