You get better mileage during cruise due to decreased pumping losses.
The large amount of advance ground into the cam lowers the peak power by increasing dynamic compression ratio. Good for low RPM.
The phaser allows for retard on the fly, generating higher peak HP numbers.

I haven't seen any advance commanded on a table yet. In my experience, the positive number was amount of cam retard. In fact, in HPTuners I believe the available range of numbers is 0-50 or something of the sort. Any advance would be negative number and wouldn't fit this range.
Now you have me confused...

Actually, the opposite.

Because VVT helps to make better power across the band. Then proceeded to explain how.
You were right that MPGs will be sacrificed if you delete VVT.
For the record, most people don't care about VVT because they don't understand it nor its potential. They would mush rather stick with what they know and put a 3000rpm stalled converter and 220-230 range duration cam and run with it. And it'll run good. I just don't like aftermarket stalls and skipping over 1/3 to 1/2 of the rpm range. I build for relative comfort.

it's based off crank rotation, not actual degree's.
short and sweet explanation of it
http://www.hptuners.com/forum/showthread.php?t=17883
to find out the exact advance/retard and build the tables accordingly, cam specs are needed. simply putting the 07-09 cam tables into a 10+ just pisses the truck off and drops power.
