New HPTuner

[rdread]

I'm new here, so be kind!
I just recently received HPTuners Std version.
I purchased it with the intent of "improving" the fuel economy, performance, and driveability of 4 of our company's vehicles: 2 07 Avalanches, 1 07 Tahoe, & 1 06 Silverado.
I've already made some positive changes to the transmission TQM on my 07 Avy, but from there, I'm pretty much lost on where and how to proceed.
I've downloaded some tunes from the repository for comparison purposes, but there aren't many for the 07's posted with any modified tunes.?
I know there are some seasoned veterans here that hopefully can guide me in the right direction.....?

The 07's  are harder to tune the VE than the 06 older.

Yup.? The 07's are different.
So, basically I'm to start with rescaling the MAF, then move to spark, then timing?
Any more tuning advice out there?

reduce PE,but you need a Wideband to be safe.
