Would reliable Mark 14 torpedoes change the Philippines campaign?

How would more reliable torpedo exploders affect the Philippines campaign?

Working Mark 14 torpedoes would help U.S. submarines, but better-performing Japanese torpedoes would also make attacks on American ships more dangerous.

Working Mark 14 torpedoes would help the U.S. Navy's submarine service. The hypothetical also gives Japanese weapons their advertised performance, increasing the danger to American ships. Improving torpedo reliability on both sides therefore prevents the American gain from being treated in isolation.
