I just recently added a Flowmaster exhaust system and a Volant Powercore to my 2007 Avalanche Z71. I am looking to add one of the above tuners within the near future but I need to be completely sold. Can someone guide me in the right direction? Im looking for ease of use, functionality, ability to customize. Im looking to try and squeeze a few more mpg from my truck although i do known a 5700lb machine will not get the mpg of a Prius.
