I purchased two credits to tune my Duramax. I would like to be able to tune more of the same which requires 6 credits. Can I buy just 4 more credits, or do I have to buy 6 credits to continue?

You can check your help-license information for the upgrade credits required.
You can open a support ticket here https://support.hptuners.com/
75% of credits spent goes towards the upgrade. So you will need 5 to upgrade.
And you know that is only for that same year.
