i have purchased a magic stick 3 cam and what i think are the necessary components. timing chain dual valve springs pushrods 30lb injectors and a ported oil pump. what is a good tune for it

I'm assuming that you have an LS1 engine, since you are using the Magic Stic 3 cam. If so, there isn't much that you can do to tune the engine, other than sending in the PCM to a company that can set it up for using 30 lb injectors. I hope that is the correct size injector, or the size that is recommended by the company (I have no idea if they are correct or not), but it seems a bit large to me. If you don't do this, the engine will run extremely rich at idle. I'd suggest: http://www.pcmforless.com

Also, you should consider using roller rocker arms, becuz the stock rocker arms have been known to fail when using high lift cams and high spring pressures.

Was going to add a U-tube video that I found of an LS1 Firebird...in Kuwait of all places, but the video disappeared on me. The guy had an LS1 modded out to 422 ci and the 3 series cam. He got on it and it was an OHMYGAWD or maybe it was an OHMYALLAH! That thing launched like it was an Atlas Missile headed for Saddam Hussein. Take that you ricers!!!

a good tune would be getting it dynotuned. but then u can order the chip at pcmforless.com
