If your choice is between HPTuners and EFILive---I would recommend EFILive. I don't like HPTuners tune credit setup or their VIN/OS match. With HPTuners the year of the OS has to match the year of the VIN. If it doesn't you can't read or write to the ECM. So, for retrofit projects that must have the vehicles VIN---HPT is out. It also appears that you can't modify a calibration unless you license it. So, if someone wants to send you a tune to look at, you can't edit that tune unless you license it for 2 credits. I don't own HPT but, that is how I understand it.
