    I am finding conflicting HP numbers for the 12.7 DDEC II. I saw a local ad for a 1991 Series 60 with 350HP and assumed it was a 11.1 liter; I didn't think a 12.7 was rated that low from the factory. But in trying to confirm this, I have found several places stating the factory HP rating for the 12.7 started @ 350 ... still some other places say 380HP.
    :biggrin_25511:
    Can anyone give a definitive low end factory HP rating?

    Second question: how much change can be made to HP and TQ settings on a DDEC II with via a reprogram?

    Thank you!

    According to Wikipedia
    I have found another website that lists the power and torque of the earliest DDECs and 350bhp is listed in the 12.7 range.

    Hope this helps!
