Our Mini Big Rig Can't Do the Speed Limit. Can We Fix It?

Today we're trying to make our 1999 International 4700 Lowpro truck go the speed limit. It's got a T444e/Ford 7.3 Powerstroke engine and an Allison transmission, and we're trying to tune the computer on it. Tuner we used: Orion Navistar tuner from Power Hungry Performance at https://gopowerhungry.com.
