MDI 2

I'm going to be ordering one soon myself.
If you are going to modify ECM or TCM calibrations go with HP Tuners. The MDI unit will not give you that ability. If you want to re-program all modules with GM calibrations then the MDI 2 is the correct path.
Currently we can modify ECM, TCM, and FSCM calibrations with HP Tuners. EFI Live has some inadequacies on this platform.
