    Default 04 LB7 Speed Limiter

    I have disabled the speed limiter on other LB7's using B0747 but with this truck when I increase the mm3 past 90mph the truck still will not go above the limiter. Is there anything else I might need to adjust without disabling B0723. On my LLY I just needed to increase the Max fuel quantity vs speed table and I can go above the trucks limited speed. Any help is appreciated!

    Does anybody have any ideas about this or suggestions on which tables to change?
