    Detroit's I've been looking at new trucks and really not wanting something under 500hp but I've been told by two different sales people that you can upgrade the ECM to 500hp on a 435hp motor.
    i asked a few people and can't get a true answer

    Yep cuz if u dont have the drive train according to their specs they wont do a thing, on my last truck with a detroit thats what happened to me,i got pissed and just sold the truck, that 435hp is a dog...i hated that motor, sucked for mileage, and u dropped 3 gears on a hill

    Yeah like Casual Trucker above said... Call Detroit Diesel with the engine's serial number and they can give you the engine's specs right over the phone.
