If you were to get the cam, i would advise to get a mail order tune, so that you can maximize the potential of your modifications. the handheld pre programmers have a very limited modified map in them, so that every vehicle can slightly benefit from it. this is so that they don't sell one ot a person with an out of whack setup that could be harmed by a blind tune (pre programmed tune, mail order or handheld) and blame it all on the company for liability reasons.

I'm a little overtired now so that last part might not have made sense, but i would suggest the cam and the mail order tune (wheatly's or TXVortec350 as he is known on this site, there are others but wheatly was a nice dude to deal with) to get a nice boost out of your truck. tell whoever you decide on to tune your ECM the specs or brand (maybe both) of your headers so that they can be adjusted for in your tune as well as the camshaft you would like.
