I am currently using 3.36 and I am very comfortable with it. However, I have some customers wanting me to tune 17/18 GM trucks and for that, I am aware I will be needing a newer version.
I currently have 2.24 installed in another laptop and my interface still works there. What would be the newest version of HP Tuners I can install on my main tuning laptop without changing the firmware that's currently on my MPVI device? I would hate to get and install 4.6 and not be able use my old laptop where I still have version 2.24 or even go back to 3.36.
