New Tune

[LLV ST]

If I get a tune and flash it back to stock before a service or warranty claim can the Ford Dealer see that it had been tuned before and void the warranty if related or harass me about the tune?
Thanks in advance

Yes they have more then one way to see that it has been tuned even if you flash back to stock. Most dealers won’t care unless it’s a really big ticket item, others will nitpick.
