Black Bear Tune

[FrankU]

Well we just got back from Bridgewater NJ getting an in person tune on our 2006 SSV 160K on the clock.
If your on the wall about getting a tune from Black Bear just do it ! The tune is WELL WORTH IT.

Advantages noticed so far :

Fuel economy is up , quite noticeably.
Performs MUCH better.
Transmission temperature lower.
Shifts nice and clean.

It was a pleasure meeting the Black Bear team , Jason and Jarrod are good folks. They did a great job on my Tahoe. I highly recommend they're service.

I was there Saturday. Definitely better shifts, highway performance is very noticeably improved, haven't checked gas mileage yet and don't want to bc I been flooring it a lot. I used to run 87 octane but I'm trying 89 to see if I get better gas mileage- performance hasn't been any better than 87 though, so prob not worth the extra cost.
How is your performance off the line? I notice that if I floor it, I kinda bog down a bit (did this before the tune too). I don't have any mods though but am getting an airraid jr soon.

All in all, truck runs much better.

Off line , slow roll the hit is fine. Airraid won't be worth it IMO.

What octane did he tune your rig for ? Gear ratio ? Tire size ?

I was accelerating more smoothly today, instead of flooring it off the line.....seemed better. I got the 87/89 octane tune. Tires are 275/55/20 and stock gear ratio (not sure, 5.3 SLT w tow package).

I'll try to explain:
The 275/55/20 tires are big. The big tires effectively lower the gear ratio. The stock gear ratio is 3:42.With your tire height your ratio was reduced to @ 2:90 (est) . That combined with a @ 5000 weight . Makes it tough to get going from a dig.

Thanks, makes perfect sense.

Eh with tow package it may have 3.73 or even 4.11's.

Mine without tow package has 3.73's. You can search by rpo code

Look at the tag on the glove compartment door. or you can put your VIN # here and get your codes to find your exact gear ratio and options etc : http://www.gm-trucks.com/rpo-code-lookup/
