Norman it really depends what kind of tune you want.
BB does tunes tailored to mpg, towing, performance, octane rating, shift points, etc ... you basically tell them what you're trying to achieve and they tailor a tune to your needs.
In my case, the clumsy denali transmission was driving me nuts hesitating/bogging down between 1 > 2 > 3, so everything was first and foremost to remedy that, then to get the most out of my engine with 93 octane fuel, mpg wasn't a priority although I was pleased that it didn't drop much ... but like I said, talk to them and they'll tell you what is possible and what you can expect.
They're good people.

Serge,
Thanks for the reply! You are right, I suppose someone buying a 6.2 V8 probably doesn't need to get 30mpg! So it might be the AFM shutter in combination with the sloppy shifting? I believe you about the "good people" comment. I have ordered an exhaust from them (very helpful). I just thought there would be more custom tune consumers that would chime in. I have seen a lot of aftermarket tuning in peoples signatures.

I have a 2011 Denali XL and never notice when it switches between 4 and 8. I'd take it back to the dealer.

The sloppy shifting is a common issue for all the 6 speed/6.2L vehicles that are 07+. I have that issue on my escalade and can't wait for a BB tune in my area.
