6.2L tune??

[kctyler]

I have an 6.2 AWD Denali. Any of you guys have one tuned? Wanting some more HP and MPGs.

You'll find many using black bear performance with great reviews. Personally, I'm taking mine to a reputable GM tuner in Delaware with an AWD dyno and getting a custom 93 tune/cold air kit. I'll be sure to post results.

Im with you. I would like to have it done on a dyno as well. I have read lots of good things about BB as well.

I used Diablo because i wanted something in my hand to change settings if need be. Iv done lots of datta logging and she is as good as I can get her now but i do plan on getting a custom diablo tune.

6.2 ≠ MPGs.

BlackBear tune will wake up sleepy OE throttle TM and shifting calibrations.

Avoid handheld 'tuners' and step up to the real deal.

I had an Edge Evolution in my 07 5.3 Tahoe...it did the trick, but I want more...

I just traded my hoe in for an awd denali 6.2 and will be getting a BB tune when tax money comes in and I can't wait.

I got mine tuned by a shop here in Los Angeles. Its a night and day difference for sure. However don't expect better fuel mileage.

Can you explain what improvements it made?

Throttle tip in, acceleration, transmission shifts are firm and are fast. That's my experience at least.
