I purchased my 2017 FiST used and it came with the Mountune MP215 package. I'm considering upgrading to a regular AP with a Stratifed/Dizzy/etc tune as I add an intercooler and such. Is it possible to buy a AP and flash over the MP215 tune (storing that MP215 tune as the "stock" tune) or would I need to go to a Ford Dealership to get tuned back to stock first?
Thanks!
