Patrick,
You can take your truck to any dealer service facility or any Cummins location. They can simply connect their computer to your ECM and reprogram the engine.
Have them remove all govenors so your speed is limited by your gear ratios only. Also, if your engine is currently set at 1,800 RPM, you may be able to increase that to 2,100.
Depending on the rating HP your N14 is currently set at, you may be able to uprate the HP and torque at the same time, (if your transmision is rated to handle the increase).
Total cost for this reprogramming should not exceed 1 hour labor.
There are many parameters that can be reprogrammed at the option of the owner. Check your engine manual for details.
