I'm about to upload my new 3bar tune and I have a question. Do I need to go back to stock first, then load the new file, or can I just program the new file? The reason I ask, is in the manual, it says that the device will read your current tune and record the "stock" setting. When I upload this newest tune, will the device think that the file I have loaded now is the "Stock" tune?
Hope this makes sense.
