I've been contemplating getting the tune from SVC. If I pick up the tune with the SCT X4 I was wondering if there's a way to tell if the ECM was previous flashed prior to applying the tune?I'm asking this because I want to make sure the factory tune gets backed up prior to applying any tune. Could I potentially take it to the dealer and ask them to flash the ECM to be sure?</blockquote>
