not if the warranty is a limited warranty (which it is) AND the warranty has words about voiding warranty if a tune is installed (which it does on later models) As long as exclusions are listed MM doesn't provide any protection for the exclusions.One thing people are overlooking, the Magnuson Warranty act the dealer has to prove the tune is what caused the failure.
Just like warranty is excluded if used in racing etc.
MM warranty act is worded around use of aftermarket parts that are used as part of the warranty requirements for maintenance. E.g. oil filters, oil etc. don't need to buy from mfg.
