XCal 2 changing tunes question
I'm new to all of this and have a question. I've loaded my 87 Tow tune. Now want to try one of the 91 octane tunes. Do I need to go back to stock and then to a 91 tune? Or can I go right straight from 87 Tow to 91 Tow? Just don't want to lose my stock tune. Thanks for a reply.

You can go straight to 91 tune, no need to return to stock, make sure you have at lease 91 octane in the tank before doing so....
