Superchips/Gibson sideswept ordered for my 5.3

Just ordered the superchips 2714 for $350, and the Gibson sideswept for $309 for my 2004 z71 tahoe through summitracing.com.  I already have the Volant intake. I read some of the posts on members with the superchips and gibson and it seemed like the way to go for me.  if anybody has any tips on configuring either of these or what to expect for hp/torque/mpg let me know.  Thanks!

Whats the superchip do for an Avlanche?  (expected hp numbers, based on intake and exhaust mod'd).

They all claim about 10hp and about 1mpg, so between intake, chip, exhaust i should get 30hp and 3mpg.  i think to get the max out of the chip you have to run higher octane though.  Tahoe and AV should be same thing, AV just weighs a bit more.
