    My friend just bought a 98, 9900 International Pro Sleeper truck and he says he can only go 66mph. He says there is a speed governor on it and he doesn't know how to disable it.
    I'm sure you may need more info on this but I'm not very familiar with the 'big' diesels so just let me know.
    Can anyone help out on this?
    Thanks so much and God bless!

    It is changed by a lap top through the ECM. With software that matches the engine brand.

    Thanks Mike for the quick reply!
    I sure appreciate you folks!
    Well, that's something I can't do myself as I don't have the software.
    Take care and God bless!

    So that's the reason, last Tuesday on I-90, a trucker pulls out in front of me to pass another truck and rode neck and neck for the next 30 miles, top speed was 66 mph, but both slowed to 61-63 up grades. Traffic between built up for miles, the trucker on the left couldn't speed up, but wouldn't slow down either, and the one on the right just stuck with him. I didn't pay attention to the truck on the right, the one blocking traffic was a ground Fed-Ex truck.

    Hope your friend gets his reprogrammed to 68 mph, very annoying when you have to cover over 500 miles in one day plus conduct business and to be blocked.

    Thanks NickD!

    Here's a simple solution to this problem. FasterTruck . com. They have a device that makes big trucks (semi and 18-wheelers) go faster. I've had one for the past 2 yrs. and it works great.

    This is my favorite quote from the web site.
    That is all the trucking industry needs right now. Trucks grossing 120,000 running around at 80 MPH. I don't care about the driver who does that. I have a 50 ton wrecker that gets paid well to pick up the pieces. What I care about is my wife and kids on the road. As well as the trucking industry as a whole and how it is perceived by the public.

    Only one reason for that product.. Truck drivers by passing the speed limits set by the company they work for. Fired for sure if they get caught. Get into an accident, and better do the stretching thing so they don't pull a muscle when kissing their own butt good bye.

    Otherwise it would be cheaper just to have the speed limits set by the dealer. Less then an hour to do, may have a one hour min charge. Dealer don't care what the speed limit is set to. But will only change it for the OWNER of the truck. No legal problem setting the speed limits on the truck. But add a product that modifies the trucks safety features and I bet that leaves one open for very bad things.

    But it's ok for your wife and kids to have the ability to speed up to any speeds they want and cut a truck off. This is the way we make a living. 76 percent of accidents are caused by the four wheeler. That is a fact. If a professional driver doesn't have the right to run at the speed limit your wife definatly does not.

    Go ahead and put a 65 MPh limiter on your minivan and maybe maybe you have the right to tell me to slow down. Oh and take yours and her cell phone away while driving so we don't have deal with your BS on the road. We pay taxes out the ass to drive our trucks on the highways do you? Next time your local store runs out of toilet paper because the truck couldn't make it there on time because it's too dangerous for your family to run the speed limit then wipe your ass with your hand.

    To all the police officers four wheeler drivers and everybody who likes to drive around texting and chatting on the phone at 75 80mph. You are the problems on the road today, and the only way to make the highways and roads safer is to get you off of them. Slowing trucks down does nothing but create more problems for us all. And I don't feel one bit bad for any of you who get into an accident while your doing it. The truth is you need to slow down and get off the road before you hurt me or my family, you are amatuer drivers and you have no idea how to maintain controll of a vehicle at 80mph plus!

    You dredged up a 9 year old thread to rant about it? And I'll assume you drive a truck "professionally". Excellent, a road raging long haul otr driver...what could go wrong?

    Have the greatest respect for truck drivers, without them, our stores would be empty. Ha back then, had guys quit on me to become truck drivers, didn't like somebody looking over their shoulders all day, this sure changed.

    Nixon was sure an idiot, dropping the speed limit down to 55, besides increased driving times, were getting poorer fuel economy. Same with my Buick at that time, at 70 mph, geared for it, was getting 20 mpg, that dropped down to 17 mpg at 55, and trying to stay awake. That idiot didn't realize 90% of the driving is done in congested city areas, had idiots in that office ever since.

    Now after some odd 42 years, driving at 70 mph again, except for many trucks, still driving at 65 mph.

    Most commercial trucks have their road speed governed by the companies they are owned by.
    Independents can change their vehicle speed parameter using the software of their engine/truck.
    Or it can be changed by the dealer.

    I can tell you that any large hauling company (Fed Ex, UPS, Safeway, etc) are probably set by their companies and their trucks can only go so fast.
    If a truck is limited, it is by limited by the company that owns it or the owner/operator.
    It can be changed for the OWNER of the truck by any dealer.
    Once thing to remember, if you change the vehicle speed setting, it will log it on the truck computer and if you set it too high and the vehicle is involved in a speed accident, they will check to see who changed the parameters and they will come to your door.

    I know this, because I just got done changing the parameter on several dozen trucks, because of speed limit changes.
