Some have suggested "truning up" the IP a bit.......
HOWEVER with added "power" you get higher EGT's VERY BAD if not monitored.
If your looking for spinning tires and smoky burnouts...... Sorry WRONG trucks.
The CUCV is a VERY strong truck as delivered, you can always "improve" it, but there will always be COSTS the farther you get from the original configuration
Most of these trucks are 25 plus years old!!
You could do a complete Engine, Trans Xfer case and frt & rear diff rebuilds.....
But you would have the same truck, just everything new and shiny.....
