I've had the SC 3865 for about 5 years now, every time I change the tune on it I set it back to "stock". I've tried to find the answer and haven't gotten through to SC support, but here it goes...
When set a tune and accept to go forward with the install it saves my OEM flash and then erases it from the PCM. My question is when I want to change my tune to another tune (i.e. going from 87 to 93) do I have to return it to stock and then upload the 93 tune or can I go from 87 to 93 without issue? I've just always been worried that it'll corrupt my OEM flash somehow and would rather try to avoid having to pay the dealer for a re-flash.
