What is involved in doing this for the ecm/tcm tune? As far as i know i just need to download some files from the car to the computer and send them to vms to modify and then they send me the modified files back to upload into car. Is this correct? also is there a program that comes with it to get the files or are there directions for the whole process?

Yes, yes and yes.

The software comes on a USB thumb-drive, there is also a sheet of simple directions.

Its fairly simple. The whole process took me less than two hrs.

1-install software on laptop/pc from usb drive
2-hook cable up to car and computer
3- open EMC program, click connect read ECM, save file when finished
4- open TMC program, click connect read TCM, save file when finished
5- email files to VMS
6- VMS will email you *mod* files for ECM & TCM
7- open EMC program, click connect install ECM mod file
8-open TMC program, click connect install TCM mod file
9- take for test drive
10- mail back flashxpress

It sounds too easy, but i like it.:)
