I would Like some Experienced opinions on benefits, drawbacks of using the stock 48 volt FICM versus the "upgraded" 58 volt FICM. Never tried the 58 volt, but would think it would give a greater margin above the minimum required voltage for injectors. Purely theoretical or does it really help? Focusing primarily on STOCK 6.0's. Thank you in advance for sharing your knowledge!
