07 yukon denali xl

[jnjhelms]

Just wondering how many ppl have done the black bear tune on an 07 gmc yukon denali xl with the 6.2 ? How much extra did it give you ? Any downsides?

We have done plenty of 07+ 6.2L Yukons, including owning one ourselves.

One major thing, with that engine, you need to be running 89+ octane even on stock tuning; higher compression dictates that.

What can I expect from the black bear tune how much hp and torque? And will it improve mpgs any?

 

[JennaBear]

Typical results are 15-20hp, 1-2mpg, and much improved shift patterns and throttle response.

Same boat. Getting air filter kit and chip. Anything else under 500 I should put in before getting the BB tune?

I am in Canada but visit Florida regularly, can you guys service my vehicle?

 

[JennaBear]

We have plenty of customers in Canada. What year is your vehicle?

People in other posts say don't bother with a chip just get the tune?

 

[JennaBear]

Not sure what you are referring to as a chip, GM stopped using chips in 95, and now use full computer I OSs.
