Hello, my name is Chris but I prefer to go by BlazeFoxKitsune. I have spent a few hours modifying 
the "super kitt" files supplied by Dragonball1957. KITT now has a cruise speed of 130 MPH. 
And a flat top speed of 200 MPH while in Super Pursuit mode.. No this isn't as fast as he was
on the show but it is quite controllable and very even. Turbo Boost was also adjusted. 
Instead of leaping insanely high in the air T.B. is now stabalized. You can jump quite far 
and also just high enough to get over the walls of the G Industries compex in the mission 
"The Bad Son."  You also land in a very stable manner as well. I also played around with the wav files, 
I used the kittsound found on DragonBall1957's website and I increased the volume. 
I also lowered the volume of the ToerenVAG file. Before the "engine" sound drowned out the 
KITT turbine engine sound. I hope these files are helpful.

The files "KITT_Data" and "kittphysics_0" go in the Vehicle folder.

The files "kittsound" and "ToerenVAG" go in the Sound folder.

I worked the ini data around my own needs. I am using a Sidewinder Dual Strike controller.
