Bill, the modification of your truck needs a plan. Too often people get caught up in the "mod of the moment." Decide what you want as an end product...is it going to be a daily driver, a full race machine, a quick street machine, or a very quick street/strip monster. Are you sure that what you have is not enough. Is your interest mainly in appearance mods, or does appearance take a back seat to performance? An example: People jump on CAI conversions because it is visually very attractive, and the sound is great. Lots of CAI builders advertise horsepower increases and that has really become a debate. Then shortly after getting a CAI some decide that they want to boost the engine and end up trying to sell their used CAI because they are going to a turbo, or supercharger...
With the end in mind, you can begin (Excuse me Stephen Covey). Decide what your objective is...
You don't say if you have a QC or a RC. That is important...what you start with in large part determines what you will be doing initially...from a performance perspective the QC owner usually gets the biggest bang initially from a pcm flash...but if you plan to supercharge or turbocharge that engine, the pcm flash will be something that will have to be re-done when you go to forced injection. The second most popular move is exhaust modification, headers, cat delete, and Magnaflow...
If you have a RC, then your initial performance approach is probably determining if you will need to move to a Centerforce Clutch with the Viper Slave and Master Cyl modification (you will have to sooner or later). Then the same exhaust approach as mentioned above.
Following these initial mods, people start dealing with engine temperature issues with a thermostat change, additional cooling mods such as fans and intercoolers.
As far as visual mods, well that comes to a taste question....anything goes except wing removal. Wing removal is tantamount to treason.
Hope this helps get you started...welcome aboard, come often and read carefully, there are lots of opinions here, and opinions are like ass holes...some stink and some don't.
