Speed problem
I have a diablo sport programer and have a problem... I have my rpms like this.. wot-1-2 5600, 2-3 5225,3-4 like 4350.. I want the best acceleration possible with it, but when i get to about 97 mph on the interstate the truck seems like it has got as fast as it will go until i get to a hill and then it will go on pass 100.. I just wonder how i can get it to move on past this speed... 4.6 engine

There is nothing wrong with your truck.
Thees truck come from the factory with a built in speed/Rev limiter. Your truck must be set at about 97 MPH.
The only way to fix it so it will go higher is with the computer. Don't no if your chip has that capability or not.
I have a custom tune and race my truck.It is set at 125 MPH or 6200 RPMs
I have hit the rev limiter one time in the 1/4 mile but that was with 410 grars and the over drive locked out.I hit 6200 RPMs.
