Now, I'm nervous to start trying to change the tune in the vcm (I'm new to everything regarding tuning). I've read that 2 credits license the pcm but once I load the base tune, won't the vin change to what's in the base tune? If so, will I have to license that vin also?
Main question is how do I get the base tune into the new pcm?
Probably a question y'all get too often but I appreciate the help in advance.
