Run a search under federal emissions laws or the Federal clean air act

Emissions Laws
The Federal Clean Air Act as amended in 1990 has extended the prohibition against removal or rendering inoperative vehicle emissions control devices by the consumer. Changing an engine or even a transmission in a vehicle may change its pollution status and render it illegal for street or even off-road use on lands that are covered by emissions laws. This usually applies to later model vehicles and this, along with other pertinent laws vary from state to state. Generally engines and associated emissions controls from vehicles that are the same year or newer vintage as the vehicle to which they are being converted are legal swaps. However, it is the owner's responsibility to investigate the smog laws and determine that any changes you make to your vehicle will not cause it to be in violation of any state and federal regulations.

Many often ask about the difficulty of installing late model engines, especially those which are OBDII compliant - which includes all engines after 1996. There are some sticky issues involved, but as interest in swaps remains so strong, many resources are available to help decipher it all. We will continue to work in this area so we may be of assistance and offer helpful products to assist with these technologically advanced conversions.

First make sure you truck is running the best it possibly can be BEFORE you install a chip or the purchase will be useless.

Complete Tuneup and timing set to base zero with the timing wire unattached from the PCM:

Fuel filter
Spark plugs AC Delco
Cap & Rotor
Air Filter
PCV Valve
Transission flush and refill and a new filter
Differential fluid and transfer case fluid change

Without doing all of these the chip won't gain a thing.

I have disassembled several HyperTech programs for early (ECM) vehicles. They really don't do much for performance. For the cost of one HyperTech off-the-shelf PROM you could be burning your own, and make it a LOT more effective than the cookie-cutter variety HyperTech:
